The document discusses various aspects of nurturing the creative process for game design. It recommends broadening one's reading on diverse topics to generate new associations and ideas. Game designers should play a wide variety of games to learn different mechanics and genres. Sources of inspiration can come from unexpected areas beyond just games or movies. Brainstorming and letting ideas develop over time are important parts of the creative process. Well-designed games involve a series of interesting choices for players with meaningful tradeoffs rather than obvious or dominant strategies.
A semester postmortem on the mindful xp project at the Entertainment Technology Center at Carnegie Mellon. Over the spring 2012 semester our project team developed 10 games with a focus on meaning and expression.
In this presentation we discuss the origins of our project, the 10 games we developed, and what we learned from our experiences about creating meaningful, expressive games.

Paideia as Paidia: From Game-Based Learning to a Life Well-PlayedSebastian Deterding
»Gamification« has sparked the imagination of many for the potential of games in education, but turned away an equal amount within the games and learning community with its disregard for the complexities of design and human motivation.
However, this talk suggests that there is a deeper reason for the negative reaction in the games and learning community: namely, that gamification really provides a distorted mirror that throws into stark relief issues in today's game-based learning at large. Conversely, that best way to advance games for learning today is to look deep into this mirror. Doing so reveals a triple agenda for the field: to expand from deploying games as interventions in systems to the gameful restructuring of systems, and from designing games to the playful reframing of situations; and to shift from the instrumentalization of play and learning to paideia as paidia.
Game Design Course Development Panel at the Foundations of Digital Games Conference held on a Royal Caribbean cruise to Cozumel, Mexico. The panel speakers were Dr. Ken Hoganson, Dr. Cynthia Calongne, Dr. Mario Guimaraes (our mastermind) and Dr. Barbara Truman. Dr. Jing (Selena) He was unable to join us. Slides by Dr. Calongne from her games and simulation design classes with Dr. Andrew Stricker at Colorado Technical University.
For all of the hype around “user experience” it often feels like we struggle with what it means to actually craft an experience. We build and ship products that are perfectly fine. We make things that are usable, attractive, responsive, reliable and whatever else has come to be expected. And yet, there’s something missing. Something intangible. It’s not obvious what’s missing, until we contrast our own work against other mediums more established than our own: Film. Game design. Storytelling. Advertising… These mediums know how to make us feel, in deep and profound ways. So how do we do the same? Are there processes we can change, or things we can do to create memorable and meaningful experiences? And who has reached this level of emotional engagement? In this session, Stephen P. Anderson will explore the subtle, but critical ways we can level up our work, bringing a depth and richness to the experiences we shape.

Experience design is not about shiny new digital technology - apps, touch screens, games, beacons, the works.

What Board Games can Teach Us about Designing ExperiencesStephen Anderson
There’s a reason so many board gamers show up UX events. The same skills that make us great information wranglers are the same things that make board games like Catan, Pandemic and yes, even Exploding Kittens so appealing! It should come as no surprise that we’ve seen prominent UX leaders cross over into board game design (Matt Leacock, Dirk Knemeyer).
If we scratch beneath the surface, there’s a set of shared skills (and struggles) common to these different professions. Specifically: the spatial arrangement of information, visual encoding of information, creating designed spaces, a systems view, playtesting / user testing, competing tensions, triggering emotional responses, and many more.
Okay, so what? Sure, it’s kind of neat that we have so much in common. But how might this change what I do at $largecompany? Here’s the honest truth: The game design profession is just a little bit farther down the road than us, and we have a lot to learn from this group if we can look past the superficial differences. We talk about designing for emotions, but let’s face it, game designers are actually winning at this. Processes? We talk about lean and agile, but game designers have mastered playtesting (and the design to playtest ratio should make us embarrassed at how little we actually iterate with users). And there’s plenty more. I’m confident that if we can look our our own profession through the lens of game design, we’ll see plenty of glaring opportunities for improvement, and a few tricks we might pick up, as well.
For all the attention given to design and UX in recent years, here’s the truth: Most companies are not set up to truly deliver an experience. Consider the rich, nuanced experiences we’ve come to expect from more mature mediums like film or game design. These experiences makes us feel, in deep and profound ways. But pulling this off requires a constant orchestration of things at the systems-level and a laser focus on incredibly fine emotional details. And speaking frankly, things like “feelings” “experiences” and “emotions” — these are intangible things. Businesses are trained to prioritize, quantify, and measure tangible things, that promise a clear payoff. We pit belief–about what will create a great customer experience— against data. Is there a reconciliation between these two mindsets?
In this session on design leadership, speaker Stephen P. Anderson will share his experiences, both as a consultant and as part of an executive team, trying to balance the needs of the business with needs of the customer. He’ll share a model — adapted from game design — that offers to balance theses kinds of “art and science” issues, promising to bring together cross-functional teams and reconcile competing interests. Taking cues from game design, this new model will give you a constructive way to think about everything from designing for emotional needs to tracking key metrics to discerning between “little e” experiences and the “Big E” experience. Walk away with a framework you can use to balance what’s right for the business with what’s right for the customer.
To be good user experience folks, we need to crack open some psych 101 textbooks, learn what motivates people and then bake these ideas into our designs.
The Golden Gamers: A 65+ Library Gaming GroupJohn Pappas
"The Golden Gamers" Equitable and Inclusive Gaming Events for the Elderly presented by John Pappas
Tabletop board gaming is a creative, multi-generational, social and fun activity. While there is a broad swatch of recreational activities for the 65+ crowd, generally gaming is left out. Conversations with the Senior Activities Board of the Upper Darby Libraries confirmed this with traditional video games providing an engaging experience but accessibility tends to be a challenge due to physical determinants (carpal tunnel, poor eyesight, arthritis) and experiential (with a large learning curve required for many video games). Tabletop board games provide an experience that is interactive, social, cognitive and engaging. With concerns over Alzheimer's and social isolation, this is an important subject for many seniors. The Primos Library instituted a series of programs "Tabletop Gaming at the Library" (intergenerational, weekly), The Game Designer's Guild (monthly, intergenerational) and the "Golden Gamers" (65+, Monthly-Weekly dependant upon interest) each providing a gaming experience for burgeoning and experienced gamers of any age.
In this talk, Pappas will discuss the initial planning, marketing, collection development and community engagement elements of the series as well as successes and challenges. A large portion of the talk will be on game selection for this age group including issues such as the level of social interaction inherent in the game, types of games, levels of complexity and iconography.

In August 2014, I was hired by the Reuther Library at Wayne State University to process 1700 linear feet of American Federation of Teachers records in 18 months. At the outset, I was concerned about some of the common complaints people have about the More Product, Less Process method, but I have found them to be manageable. Included in this poster are explanations of some of the issues I have encountered and how I have dealt with them. Overall, I have found MPLP to be very effective and I am on track to finish this project on time.
DevOps is a large part of a company of any size. In the 9+ years that I have been a professional developer I have always taken an interest in DevOps and have been the "server person" for most of the teams I have been a part of. I would like to teach others how easy it is to implement modern tools to make their everyday development and development processes better. I will cover a range of topics from "Stop using WAMP/MAMP and start using Vagrant", "version control isn't renaming files", "Automate common tasks with shell scripts / command line PHP apps" and "From Vagrant to Production".

Marvin neemt je in deze presentatie mee in de voordelen van non-endemic advertising op retail media netwerken. Hij brengt ook de uitdagingen in beeld die de markt op dit moment heeft op het gebied van retail media voor niet-leveranciers.
Retail media wordt gezien als het nieuwe advertising-medium en ook mediabureaus richten massaal retail media-afdelingen op. Merken die niet in de betreffende winkel liggen staan ook nog niet in de rij om op de retail media netwerken te adverteren. Marvin belicht de uitdagingen die er zijn om echt aansluiting te vinden op die markt van non-endemic advertising.

3. Nurturing the Creative Process
• Creativity is not intellectual anarchy
• Thoughts are associative – generate new ideas by
combining others (picture of lattice of association)
– Trick is to notice patterns in association
– Say, similarity between post office delivery and
network traffic routing
• Facilitate creative process
– Stuff head with concepts and associations
• Can’t notice association between Post Office and
Network Routing if don’t know anything about either
– How? Read (All great game designers?)
Based on Ch 7, On Game Design, by Chris Crawford and Ch 2.2, The Game Development Process
4. Nurturing the Creative Process -
Read
• Make reading a lifelong process
• Broaden your reading
– More than SciFi and Fantasy books
– History, Religion, Politics, Culture
– Game Design books
• Wonder as you read (“Why is the sky blue? Why
do some coins have serrations on their edges?…”)
– Tightens up Web of associations
• Find answers to “wonders”
– Once you find why sky is blue, will tell you why
sunset is red (tightens associations further)
• Help build overall creative foundation
Based on Ch 7, On Game Design, by Chris Crawford and Ch 2.2, The Game Development Process
5. Nurturing the Creative Process –
Play Games
• More than computer games – board games
– Columbia Games, Avalon Hill, RPGs
– Example: LOTR Confrontation, Reiner Knizia
• Even computer games, broaden
– Pick titles you would not otherwise play
– Like FPS games? Fine. But try different genres
– Become a “student” of games. Learn from
them.
– Bargain bin, even, maybe not great games but
maybe great ideas
Based on Ch 7, On Game Design, by Chris Crawford and Ch 2.2, The Game Development Process
6. Nurturing the Creative Process –
Sources of Inspiration
• Perhaps games not as broad as film
– Shoot ‘em ups like “Alien”
– RPG’s like “D&D”
– Safe: “It’s like Medal of Honor but in Desert
Storm” … how creative is that?
• Draw upon wide range of sources for inspiration
– Opera, Movies with subtitles, Random lectures,
scuba diving … anything to remove stale thinking
• Originality in gameplay, story, setting, interface …
– Freshness to one, great game
– Freshness to all, new genre!
• Stephen King – originality when put familiar
together in unexpected ways
– Ex: vampire in pirate setting (turns to shark)
Based on Ch 1, Game Architecture and Design, by Rollings and Morris
7. Nurturing the Creative Process -
Brainstorm
• Brainstorming has been much studied, and
there have been found some common
elements
• Intense emotional involvement
– Care about problem
• Creator struggles, mightily, but fails
• Quiescent period, creator is distracted
• Finally, brainstorm itself and solution leaps
to forefront
– It may even seem obvious at that time
Based on Ch 7, On Game Design, by Chris Crawford and Ch 2.2, The Game Development Process
8. Having the Idea
• “How many industries can claim to deal in
daydreams?”
– Dreams are where every game begins
• With an idea, don’t implement or tie down to
technology
• “Genius is 1% inspiration, 99% perspiration” –
Edison
– Enjoy the 1% because everything else is hard work
• Think of many raw ideas to throw into game
– May come up with hybrid
– Look at what can contribute to others so get
emergent game
Based on Ch 1, Game Architecture and Design, by Rollings and Morris
9. Nurturing the Creative Process –
Growing the Idea
• Most ideas shouldn’t grow further
– Just because it is a creative idea, does not
mean it is a good one
• Be aggressive at this point in your own mind
in ripping into your own idea
– Others soon will, so you should first
• Then, when pushing the idea (to, say, a
publisher) through to a concept, make sure
can “protect”, perhaps with partner
politically skilled
Based on Ch 7, On Game Design, by Chris Crawford
10. The Creative Process – The
Beginning
• Once you have an idea
– Is it really good?
– Worth spending time and money on?
– Even if “rehash” should bring improvement
to original and new challenges
– Discuss with someone that can appreciate
the idea
Based on pages 233+, Gameplay and Design, by Kevin Oxland
11. The Creative Process – Define the
Product
• Consider target audience
• Gather feedback from colleagues
• Think about core objectives
• List the challenges
– Will help determine genre
• Determine how player will interface
• Define unique features, essential to gameplay
– Has features been done before? If not, is there a
reason why not?
• Consider theme (not graphical theme)
• Solidify in two- to three-page document
Based on pages 233+, Gameplay and Design, by Kevin Oxland
12. The Creative Process – Involving
Others
• Never design by committee
– “The only useful document ever designed by a
committee is the constitution”
– But blend of “like-minded” people can be very
effective
• Meet with team with one-pager
• Keep early meetings focused on design and not on
technical
• Write all ideas down, may come in handy later
• Incorporate changes into 2-3 page document
• Move on to Concept Document
Based on pages 233+, Gameplay and Design, by Kevin Oxland
14. Core Design
• Topics
– What is a Game
– Gameplay
– Interactivity
– Game Balance
– Look and Feel
Based on Game Architecture and Design, by Rollings and Morris
15. What is a Game? (1 of 3)
• Movie? (ask: why not?)
no interaction, outcome fixed
• Toy? (has interaction … ask: why not?)
no goal, but still fun (players can develop own goals)
• Puzzle? (has goal + interaction … ask: why not?)
strategy and outcome is the same each time
“A computer game is a software program in which one or more players make decisions
through the control of game objects and resources, in pursuit of a goal.”
• Definitions (from Ch 2.2):
– Play - Interactions to elicit emotions
– Game - Object that provides rule-bound play
– Frame - The border of a game’s context
• Inside the frame is in the game
• Outside the frame is real life
– Aesthetics - Emotional responses during play
– General enough to cover everything
Chapter 2.2, Introduction to Game Development
16. What is a Game (2 of 3)
• A Computer Game is a Software Program
– Not a board game or sports
– Consider: chess vs. soccer vs. Warcraft
• Ask: What do you lose? What do you gain?
– Lose: 1) physical pieces, 2) social interaction
– Gain: 1) real-time, 2) more immersive, 3) more complexity
• A Computer Game involves Players
– “No, Duh”. But stress because think about audience.
The game is not for you but for them.
– Don’t just think about your story or the graphics or the
interface, but consider the players.
– Ex: complicated flight simulator (say, you are a flying
geek) but audience is beginner
Based on Tutorial: What is a Good Game?, by Mark Overmars
17. What is a Game (3 of 3)
• Playing a Game is About Making Decisions
– Ex: what weapon to use, what resource to build
– Can be frustrating if decision does not matter
– Want good gameplay (next major topic)
• Playing a Game is About Control
– Player wants to impact outcome
– Uncontrolled sequences can still happen, but should
be sparing and make logical
– Ex: Riven uses train system between worlds
• A Game Needs a Goal
– Ex: Defeat Ganandorf in Zelda
– Long games may have sub-goals
– Ex: recover Triforce first, then Sword of Power
– Without game goals, a player develops his/her own
(a toy)
Based on Tutorial: What is a Good Game?, by Mark Overmars
18. What a Game is Not (1 of 2)
• A bunch of cool features
– Necessary, but not sufficient
– May even detract, if not careful, by concentrating
on features not game
• A lot of fancy graphics
– Games need graphics just as hit movie needs special
effect … but neither will save weak idea
– Again, may detract
– Game must work without fancy graphics
– Suggestion: should be fun with simple objects
“When a designer is asked how his game is going to make a difference,
I hope he … talks about gameplay, fun and creativity – as opposed
to an answer that simply focuses on how good it looks” – Sid Meier
(Civilizations, Railroad Tycoon, Pirates)
Based on Chapter 2, Game Architecture and Design, by Rollings and Morris
19. What a Game is Not (2 of 2)
• A series of puzzles
– All games have them
– But not gameplay in themselves
– Puzzles are specific, game systems spawn more
generic problems
• An intriguing story
– Good story encourages immersion
– But will mean nothing without gameplay
– Example: Baldur’s Gate, linear story. Going wrong
way gets you killed. But not interactive.
Interaction in world all leads to same end.
Based on Chapter 2, Game Architecture and Design, by Rollings and Morris
20. Games are Not Everything
• Most important … is it fun, compelling, engaging?
– And these come from a superset of games
• Computers are good at interactivity
– Allow for interactive fun
– Interactive Media and Game Development
• Examples:
– SimCity - very compelling, but mostly no goals.
More of toy than a game, but still fun.
– Grim Fandango - good visuals, story, etc. But need
to do puzzles to proceed. Could have skipped to
just watch story. Would still have been fun without
the gameplay.
22. Approaching Game Design
• Used to be thought that could not teach game
design … more of an art
– But you can teach art! (AR1000 + …)
• Even to art, there are technical disciplines such as
in music, film, poetry
• So, consider computer game designs as are an art
form
Game design practices can be taught
Chapter 2.2, Introduction to Game Development
23. Game Theory
• Some designers approach Game Theory thinking it
will help design games
– Rather, it is a theory about games are played
• Game theory is …
– Branch of economics
– Systems governed by rules
– Mathematically analyzed to determine payoffs of
various end points.
• Game theory assumes rational players
– Abstract model players – not real people
• Always try to maximize their potential utility
• Solve problems using pure logic
• Always fully aware of the state of the game
Chapter 2.2, Introduction to Game Development
24. Gameplay
• Gameplay
– Collective strategies to reach end points of game theory
– Specific to game activities
– “What the player does”
• Includes
– Utility - A measure of desire associated with an outcome
– Payoffs - The utility value for a given outcome
– Preference - The bias of players towards utility
• Note, gameplay is not everything
– Choice of car in GTA is not always about payoff, but about what is fun
– Software doesn’t have to have gameplay to be entertaining … consider
SimCity
• No one expects gameplay in movies or plays
– Who says: “Hey, where is the gameplay in Hamlet?”
– Rule 1: It should be fun (entertainment)
– Rule 2: It should be interactive (make use of computer, else perhaps
use film)
– Rule 3: It can have gameplay (but that is choice)
Based on Chapter 3, Game Architecture and Design, by Rollings and Morris
25. Gameplay Example (1 of 2)
• Adventure game: knight, dwarf, priest, thief
• During combat, knight and dwarf in front, thief fires
arrows
• Priest casts spells (assume all cost the same)
– E-bolts (do damage equal to sword)
– Band-aids (heal equal to sword)
• Which spell should Priest cast?
– Ask: against single opponent (they are equal)
– Ask: against opponent with 6 arms (bolts)
– Ask: against many opponents with weak attacks (band-
aids)
Can always decide which is better
• Not so interesting
Based on Chapter 3, Game Architecture and Design, by Rollings and Morris
26. Gameplay Example (2 of 2)
• Now, suppose
– Band-aids still affect single target but e-
bolts have an area affect
– E-bolts do less damage, but armor doesn’t
make a difference
• Now, which spell should Priest cast?
– Answer isn’t as easy. Interesting choices.
Good gameplay.
“A game is a series of interesting choices.”
- Sid Meier (pirates, civilization…)
Based on Chapter 3, Game Architecture and Design, by Rollings and Morris
27. Implementing Gameplay (1 of 4)
• Choice
– A question asked of the player
• Outcome
– The end result of a given choice
• Possibility space
– Represents the set of possible events
– A “landscape” of choice and outcome
Chapter 2.2, Introduction to Game Development
28. Implementing Gameplay (2 of 4)
• Choices must be non-trivial, with upside and
downside
– If only upside, AI should take care of it
– If only downside, no-one will ever use it
• Note, this is only regarding game theory
– Ex: Could have ray gun that plays music. “Cool”, but
soon “gimme the BFG”
– Ex: Nintendo’s Smash Bro’s has “Taunt” … ask: what
for?
– Ask: other examples from popular games?
• Gameplay value when upside and downside and
payoff depends upon other factors
– Ex: Rohan horsemen, but what if other player
recruits pikemen?
– Ex: Bazooka, but what if other player gets out of
tank?Based on Chapter 3, Game Architecture and Design, by Rollings and Morris
29. Implementing Gameplay (3 of 4)
• Well-designed choice
– Often desirable and undesirable effects
– Should relate to player goals
• Qualities of Choice (from book, Ch 2.2)
– Hollow – lacking consequence
– Obvious – leaves no choice to be made
– Uninformed – arbitrary decision
– Weighted – good and bad in every choice
– Dramatic – strongly connects to feelings
– Immediate – effects are immediate
– Long-term – effects over extended period
– Orthogonal – choices distinct from each other
Chapter 2.2, Introduction to Game Development
30. Implementing Gameplay (4 of 4)
• Should be series of interesting choices
• Ex: Use of health potion now may depend upon
whether have net for capturing more fairies
• Having net may depend upon whether needed space
for more arrows for bow
• Needing arrows may depend upon whether killed all
flying zombie bats yet
• Hence, well designed game should require strategy
• Game must display complexity
– But doesn’t mean it must be complex!
• Don’t make too many rules. Less if more.
• Real world example: termites place one piece of mud.
Results in hive, with cooling vents, etc.
– Emergence from interaction of rules
• Ex: Priests convert, but not if already in combat
• (Me: see what game)
• Ask: examples from popular games?
Based on Chapter 3, Game Architecture and Design, by Rollings and Morris
31. The Dominant Strategy Problem
• Articles with “10 killer tactics” or “ultimate
weapon”
– Ask: what are these doing?
Taking advantage of flaws in the game design!
• Should never have a option not worth using
– Dominated strategy
• Should never have an option that is so good, it is
never worth doing anything else
– Dominant strategy
Based on Chapter 3, Game Architecture and Design, by Rollings and Morris
32. Near Dominance
• Worth looking for near dominance, too
– Near-dominated – useful only very narrow
circumstance
– Near-dominant – used most of the time
• Ex: stun gun only useful against raptors, so only
useful on raptor level (near dominated)
– Do I want it used more often?
– How much effort on this feature?
– Should I put in lots of special effects?
• Ex: flurry of blows most useful attack (near
dominant) by Monk
– Should we spend extra time for effects?
Based on Chapter 3, Game Architecture and Design, by Rollings and Morris
33. Avoid Trivial Choices (1 of 2)
• Horsemen Archers Pikemen
– Transitive, not so interesting
• Horsemen Archers Pikemen Horsemen
(picture)
– Ask: what game does this look like? (rock-paper-
scissors)
– Intransitive, more interesting
– Ex: from LOTR Battle for Middle Earth
• Horsemen fast, get to archers quickly with lances
• Pikemen spears hurt horsemen bad
• Pikemen slow, so archers wail on them from afar
(Will look at game balance in depth, next topic)
Based on Chapter 3, Game Architecture and Design, by Rollings and Morris
34. Avoid Trivial Choices (2 of 2)
• A beats B, B beats C, C beats A (could hardwire)
– But could also have how much better
1) Single horseman can beat any number of archers:
Horseman Archers (∞)
2) Single horseman barely beat an archer:
Horseman Archers (1.1)
• Ask: Which is better?
– Trick question! Both are bad
Case 1) equal number of each, all others lose
Case 2) doesn’t matter which you choose
• Don’t want to hardwire. Sometimes A way better
than B, sometimes a bit better, sometimes worse
– The answer should depend upon the game situation,
weather, terrain, time … also what opponent is doing
Based on Chapter 3, Game Architecture and Design, by Rollings and Morris
35. Environment + Rules = Gameplay
• Battle of Hastings, 1066 A.D.
• King Harold tired, mostly infantry
• Duke William more archers, cavalry
– Archers beat slower infantry game over
• Not quite … Harold on hill (arrows less effective)
and defensive mode
– Archers tire game over
• Not quite … William also smart, cavalry approach, but
retreat. Infantry break ranks since they are
frustrated, charge
– Arrows now shred Infantry Harold loses, game over
• Point: ways to change balance between different
troop types. “A good commander isn’t the one with the best
army; he is the one who knows how to use it best”
http://www.battle1066.com/
Based on Chapter 3, Game Architecture and Design, by Rollings and Morris
36. Ensuring Interesting Choices (1 of 3)
• Ex: Elite (early ’80s, ask: who played?)
– Accumulate wealth by trading
– When 1000 credits, trade lazer for better
lazer and have 400 left over for trading.
No brainer. Always a win.
– What if could buy lazer with 600? Then no
credits left over. Decision is tougher.
• Point: keep difficult choices in hands of
player
• Ask: other examples?
Based on Chapter 3, Game Architecture and Design, by Rollings and Morris
37. Ensuring Interesting Choices (2 of 3)
• Kinds of choices in gameplay can involve options:
1) Should sometimes be taken, sometimes not
2) Timing is critical and depends upon context
(upgrade armor or build more troops)
3) Makes little difference whether taken or not
4) Always worth taking (target nearest)
5) Never worth taking (remove armor, pay guy for
tapestry in Vici)
• First and Second most interesting
• Third valid, but really only “chrome”
• Fourth should be handled by AI
• Fifth should seriously consider removing
Based on Chapter 3, Game Architecture and Design, by Rollings and Morris
38. Ensuring Interesting Choices (3 of 3)
• Interesting choices require good judgment
on the part of the player
– Correct choice must vary with circumstances
• Aim as designer, ensure circumstances don’t
stagnate and have only one right way to win
• No method for finding “best” choices
– That’s where creativity comes in (art)
• Still, some tips …
Based on Chapter 3, Game Architecture and Design, by Rollings and Morris
40. Strategic versus Tactical (1 of 3)
• Strategic choices affect course of game
over medium or long term
– Tactical choices apply right now
– Ex: build archers or swordsmen (strategic)
– Ex: send archers or swordsmen to defend
against invading force (tactical)
• Strategic choices have effect on tactical
choices later
– Ex: if don’t build archers, can’t use
tactically later
Based on Chapter 3, Game Architecture and Design, by Rollings and Morris
41. Strategic versus Tactical (2 of 3)
• Ex: StarCraft
– Strategic choice: 1) upgrade range of
marines, 2) upgrade damage, or 3) research
faster fire
– Which to choose?
•If armored foes, Protoss Zealot, more
damage
•If fast foes, Zerglings, maybe faster fire
– Other factors: number of marines, terrain,
on offense or defense
Based on Chapter 3, Game Architecture and Design, by Rollings and Morris
42. Strategic versus Tactical (3 of 3)
• Ex: Warzone 2100 (ask: who played?)
– Build factories to spawn war machines
– If build in level, then spawn quickly but
factory only used for that level
– If build at base, spawn slowly (have to ship to
front lines) but factory can be used in
subsequent levels
• Lesson: Good gameplay should have different
choices leading to different kinds of payoff
– Reduces the risk of trivial choices
– Increase scope for good judgment
Based on Chapter 3, Game Architecture and Design, by Rollings and Morris
43. Supporting Investments
• Often game has primary goal (ex: beat enemy) but
secondary goals (ex: build farms for resources)
• Some expenditures directly impact primary goal
(ex: hire soldier), while others indirect (ex: build
farm) called supporting investments
• Primary goals are “one-removed”
– Ex: improve weapons, build extra barracks
• Supporting goals are “two-removed”
– Ex: build smithy can then improve weapons
– Ex: research construction lets you build smithy and
build barracks (two and three removed)
• Most interesting since strategic
• Payoff will depend upon what opponents do
Based on Chapter 3, Game Architecture and Design, by Rollings and Morris
44. Versatility (1 of 2)
• Rule of thumb is to ask what is best and worst
about choices:
1) This move does most damage, but slowest
2) This move is fastest, but makes defenseless
3) This move best defense, but little damage
4) This neither best nor worst, but most versatile
• Most should be best in some way
• Versatile good for
– beginners
– flexibility (against unpredictable or expert
opponent)
Based on Chapter 3, Game Architecture and Design, by Rollings and Morris
45. Versatility (2 of 2)
• Ex: beam can mine asteroids and shoot
enemies
– Versatility makes it good choice
• Speed is common way for versatility
– Don’t make fast units best
• If a versatile unit is also cheapest and
most powerful no interesting choice
– (See “Compensating Factors”, next)
Based on Chapter 3, Game Architecture and Design, by Rollings and Morris
46. Compensating Factors
• Consider strategy game where all units impeded by
some terrain
– Ships can’t go on land, tanks can’t cross water, camel
riders only in dessert
• Assume flying unit that can go anywhere (Ask: how
to balance?)
1) Make slow
2) Make weak, easily destroyed
3) Make low surveillance range (unrealistic)
4) Make expensive
• Note, last choice common but uninteresting since
doesn’t change tactical use
• Choice should be clear to player. Don’t make a
gamble before they know.
– Ex: pick troops (cold weather) then find in jungle
Based on Chapter 3, Game Architecture and Design, by Rollings and Morris
47. Impermanence (1 of 2)
• Some permanent (ex: you get to treasure first),
others not (ex: I got storage near mine, but you
can grab it off me)
• Really, another kind of compensating factor
– I.e. – impermanence can compensate for something
being really good
• Can be used for interesting choices
– Ex: choice of medium armor for rest of game or
invulnerable for 30 seconds?
• Advantage (or disadvantages) can be impermanent
in number of ways:
Based on Chapter 3, Game Architecture and Design, by Rollings and Morris
48. Impermanence (2 of 2)
• (Examples mostly from Magic the Gathering –
Battlegrounds)
– Can be destroyed (enchantments, ex: gratuitous
violence makes units tough, but can be destroyed)
– Can be stolen or converted (ex: threaten steals or
converts enemy for short time)
– Can be applied to something you don’t always have
(ex: goblin king gives bonus to goblins, but must have
goblins)
– Certain number of uses (ex: three grenades, but
grenade spamming)
– Last for some time (wears off, ex: Mario
invulnerable star)
• Common in games, but deserves special attention
Based on Chapter 3, Game Architecture and Design, by Rollings and Morris
49. Shadow Costs (1 of 2)
• In a game, continually presented with costs
and trade-offs. But not all direct.
– Ex: soldiers for gold, but need armory first
for weapons and barracks for soldiers
– Called shadow costs for supporting
investments
– Can make flow chart mapping shadow costs
Based on Chapter 3, Game Architecture and Design, by Rollings and Morris
50. Shadow Costs (2 of 2)
• Ex: Age of Mythology has wood and food. Food is
inexhaustible, wood is finite
– Charioteer
• Costs 60 wood, 40 food and 40 seconds to spawn
• Shadow costs vary over game
– Early on, food and wood expensive, spawn doesn’t
matter
– Mid-game, much food and wood, spawn makes it
harder to pump out new units
– End-game, no wood, spawn is priceless
• Use variability to add subtlety to game. Vary
environment and vary shadow costs (ex: more trees
to vary cost of wood)
– Challenge for level designer
– Expert players will appreciate
Based on Chapter 3, Game Architecture and Design, by Rollings and Morris
51. Review: Use Tools from Toolbox of
Interesting Choices
• Strategic versus Tactical
• Supporting Investments
• Versatility
• Compensating Factors
• Impermanence
• Shadow Costs
• Groupwork:
– Use 1-2 in a game about graduating from college.
Discuss.
52. Synergies (1 of 2)
• Positive Feedback
– Economies of Scale –
the more of one type,
the better (ex: wizards
draw strength from
each other)
– Economies of Scope –
the more of a set, the
better, or advantage of
combined arms (ex:
trident and net,
infantry and tanks)
• Negative Feedback
– Diseconomies of scale –
first is most useful,
others have less
benefit (ex: diminishing
returns from more
peasants entering a
mine since get in each
other’s way)
– Diseconomies of scope –
(ex: mixed troops go
only as fast as slowest)
Synergies are interaction between different elements
of player’s strategies (note, terms may be different than ch 2.2)
53. Synergies (2 of 2)
• Ideally, all go together at once, but can emphasize
– Ex: Chess is a game of positive feedback
– Small advantage early on, exploited to crushing
advantage
• Game of negative feedback needs other ways to
keep interesting
– Ex: trench combat makes a “catch-up” factor, or as
get far from base, supply long grows, game lasts a
long time
– Ex: Super NES NBA Jam – catch up setting as an
equalizer
• Be aware of each
54. Final Word on Gameplay
• Need to make sure choices interact
– Ex: no fun winning just because out-
optimize guy on resource production
– Ex: no fun if winning just because know
right thing to do else lose no game, just
forgone conclusion
• Want choices to interact with choices of
opponent, want it to depend
55. Interactivity versus Gameplay
• Gameplay is important because it allows you to take the
experience someplace
• Ex: Kick the soccer ball around, practice headers, bicycle
kicks, etc. (interactivity)
– Play a game of soccer on the pitch (interactivity +
gameplay)
– Can you have gameplay without interactivity? Maybe.
But even so, gameplay without interactivity could be fun
(ie- television), but would start wondering if time is
better spent doing something else
• Interactivity is more important that gameplay
– Interactivity without gameplay can be fun
• Ex: Black and White, Sims
• Interactivity is the heart and soul of entertainment
software
Based on Chapter 3, Game Architecture and Design, by Rollings and Morris
56. Kinds of Interactivity (1 of 2)
• Can interact in many ways – game designers
sometimes restrict themselves to facts
– Ex: if you hit w/BFG, do 50 points damage
• Think broadly. Player could potentially:
1) Directly control characters (Ex: move Laura Croft)
2) Affect world (Ex: make Stronghold guys “insane”)
3) Influence characters actions at one remove (Ex:
give weapons, like Zeus to a hero)
4) Influence at two removes (Ex: provide inspiration,
like a Muse)
5) Decide who to follow, rather than what to follow
(Ex: observer mode)
6) Select what parts are interesting and give more
time to that (Ex: like a child with a bedtime story,
Saahil likes the hero build up and powers most)
Based on Chapter 3, Game Architecture and Design, by Rollings and Morris
57. Kinds of Interactivity (2 of 2)
• (Ask: others?)
• In the above list, how many are done?
– 1 most everything, 2 for changing difficulty
• But many not done:
– Why can’t you say to computer opponent:
• “Hey, let’s build up a big army before we fight” or
• “Don’t attack me since I’m having fun building”
– Or, why can’t you switch sides in a battle?
• Avoid making mutant versions of films, novels or
even board games
– Use imagination for interactivity
Based on Chapter 3, Game Architecture and Design, by Rollings and Morris
58. Concentrate on “Why” not just “What”
• Doesn’t have to be about what happens
– Ex: ER. Noah Wylie is avatar. With a sick patient – does
he … follow rules, give experimental drug, play basketball?
– But … not only way to be interactive. Instead, follow Noah,
switch to patient, go to other Dr., back to Noah (learn
about characters, the “Why”)
• Drama unfolds because of understanding of
characters
– True in non-interactive drama, so true in games, too
– Ex: D&D dungeon, series of rooms w/monsters. Much
richer if “why” behind scenes. Why were dwarves
there? Why did they die? How orcs break in?
• Goal of entertainment is to make audience care
– Use interactivity as a way to powerful technique to help
this
59. Core Design
• Brief, since overlaps material in
– IMGD 1000. Critical Studies of Interactive
Media and Games
• Topics
– What is a Game (Overmars + Ch2)
– Gameplay (Ch 3)
– Game Balance (Ch 5)
– Look and Feel (Ch 6)
Based on Game Architecture and Design, by Rollings and Morris
60. Game Balance - Introduction
• Beauty in balanced games
– Like Rolls Royce or Ball Machine in Airport
• Game without balance often unsatisfying and
wasted effort (parts not in balance not used, so
wasted effort)
• Broadly, game balance includes:
– Player-Player – advantage only in skill (can be luck,
but should be equal to both)
– Player-Gameplay – learning curve matched by reward
– Gameplay-Gameplay – Composite longbow does twice
damage, should cost twice $
Based on Chapter 5, Game Architecture and Design, by Rollings and Morris
62. Player/Player Balance (1 of 2)
• Ex: Virtua Fighter (ask: who has played?)
– Say, Sarah Bryant beats Lion every time?
– Does that mean unbalanced?
• No, look more closely
• Suppose friend said could beat everyone as Sarah
Bryant all the time. Would say “prove it”
– Would only be a problem if beginner as Sarah always
beat expert as Lion
– And if could choose characters? Sarah versus
Sarah?
Based on Chapter 5, Game Architecture and Design, by Rollings and Morris
63. Player/Player Balance (2 of 2)
• Allow to arrange victory by skill and judgment
• Avoid results mostly as stroke of luck
– Right from the start or magnified as game
progresses (ex: start close to gold mine provides
escalating advantage)
• Simplest way is to have symmetry
– Same weapons, maneuvers, hit points (sports do
this)
– (But note, not always the most interesting. Want
different moves on fighters, say. More later.)
Based on Chapter 5, Game Architecture and Design, by Rollings and Morris
64. Symmetry - Example
• Two heroes square off for duel, poised in kung fu
stance
• Hours pass. Days pass.
• Breeze comes by, spec of dust in one’s eye
• Blinks, frowns then bows
• Know result without fight … tiny asymmetry
enough to decide outcome
• If breeze or dust decided game, is that ok?
– No … you’d want your money back!
• Don’t want to decide by factors out of control
– Keep symmetric
Based on Chapter 5, Game Architecture and Design, by Rollings and Morris
65. Symmetry
• Symmetry is fine in abstract games (ex:
chess, even basketball)
• In realistic games, would be problem (ex:
U.S. versus Iraq, game symmetry would be
bothersome since not realistic)
• While easy, kind of an insult
– Ex: LOTR BfME Warg’s same as horses …
but Wargs can bite in book/movie!
• Better is functional symmetry that is not
obvious
Based on Chapter 5, Game Architecture and Design, by Rollings and Morris
66. Symmetry in Level Design
• Can avoid obvious symmetry
– Ex: each player has impassible region on flank
(water or mountain range)
• Knights and soldiers can’t cross
• Later on, advanced units can cross
• Choice of unit depends upon barrier
– Mountaineers to storm, ships to cross sea
– Or bluff, and then go up middle
• Players can choose asymmetric start location
– Should not be deciding factor (Ex: you choose
downwind port, so you lose)
– Avoiding making start location critical decision
– Ex: potential mines in many spots, so not critical
Based on Chapter 5, Game Architecture and Design, by Rollings and Morris
67. Symmetry in Game Design (1 of 2)
• Make all choices for players functionally
the same
– Ex: Warcraft 2 – humans have griffons and
orcs have dragons; both flying toughies.
• But even slight differences make
interesting
– Ex: Warcraft 2 – orc player’s runes explode,
making use in mountain passes good
• “Just broken” asymmetry easier to manage
than total asymmetry (can compensate)
Based on Chapter 5, Game Architecture and Design, by Rollings and Morris
68. Symmetry in Game Design (2 of 2)
• Making choices for players different, yet balanced
is tougher
• Ex: Starcraft: Protoss, Zergs, Terrans – all very
different (Same with Command and Conquer –
Generals)
– Imagine the hours of playtesting!
– Recommend only for deep pockets
– Starcraft is often a “benchmark” against which to
judge other RTS game balance
• Also, if re-creating historical simulation, tradeoff
between fairness and authenticity
– Ex: Conquistadors vs. Aztecs – Aztecs are doomed,
but may be no fun. Certainly not symmetric
Based on Chapter 5, Game Architecture and Design, by Rollings and Morris
70. Player/Gameplay Balance –
Introduction (1 of 2)
• Means remembering that the business is
about interactivity – think about player’s
relationship to the game
– Ex: If had to “tune” the T.V. every time
channel surf, would not do it much
– Likewise, should not struggle for small
reward
• Ex: Baldur’s Gate (ask: who’s played?)
– Attributes are 3-18 (ask: why?), can re-roll
if don’t like. So, re-roll until all 18’s. Ugh.
Test of endurance!
Based on Chapter 5, Game Architecture and Design, by Rollings and Morris
71. Player/Gameplay Balance –
Introduction (2 of 2)
• Player/Gameplay balance entails balancing
challenges against player’s improvement curve
– Many RPG’s have monsters get tougher with level
• Ex: Diablo 2 does this
• But boring if that is all since will “feel” the same
– Want widening options, too
• Ex: character gets more abilities
• Three rules
1) Reward the player
2) Let the machine do the work
3) Make a game that you play with, not against
Based on Chapter 5, Game Architecture and Design, by Rollings and Morris
72. Reward the Player
• Player will have to learn. Will make mistakes
(discouraging). Want to offset with reward when
do something right
• Ex: Virtua Fighter, takes longer to learn
complicated moves
– Sarah’s backflip. Reward comes from seeing flip
(eye candy) and punch in kidneys (payoff)
• Best when expand game options
– Ex: “Now with backflip, I can see new use for
reverse punch”
• In general, better to reward player for something
right than punish for something wrong
– Punishment makes players not want to play
Based on Chapter 5, Game Architecture and Design, by Rollings and Morris
73. Let the Machine do the Work
• Interface should show player the world and let him/her
manipulate
• Computer is tool to take care of wide-range of tedious tasks
– If tasks are not fun, don’t make player do them
• There is a blur of boundary between chore and game feature
– RPG could provide graph so player can manually draw map
as explore … but is that fun?
– Ex: In D&D, can tell D.M. “we go back to the dungeon
entrance”. Easy, fun. What if a game makes player walk
back over map that has been seen? Boring, no fun.
– Ex: Myst provided lightning bolt move to avoid tedium
– (Ask: other examples?)
• Also, if game option is no-brainer, consider AI taking care of
it
Based on Chapter 5, Game Architecture and Design, by Rollings and Morris
74. Make a Game that you Play With,
Not Against
• Consider great story, graphics, immersion but
only progress by trial and error … is this fun?
• Ex: crossbowman guards exit
1. Run up and attack. He’s too fast. Back to save
point (more on save points next).
2. Drink potion. Sneak up. He shoots you. Back to
save.
3. Drop bottle as distraction. He comes looking.
Shoots you. Back to save.
4. Drink potion. Drop bottle. He walks by you. You
escape!
– Lazy design!
• Should succeed by skill and judgment, not trial
and error
Based on Chapter 5, Game Architecture and Design, by Rollings and Morris
75. Specific Example -
The Save Game Problem (1 of 2)
• Designer talking about RPG
– Designer: “I’ve got a great trap!” … platform goes
down to room. Player thinks treasure but really
flame throwers. Player is toast!
– Tester: “What if player jumps off?”
– D: Thinks it’s a loophole … “Ok, teleport in then
toast”
– T: “What is the solution?”
– D: “There isn’t one.” (surprised) “It’s a killer trap.
It will be fun.”
– T: “So, there’s no clue for player? Charred remains
on platform or something?”
– D: “No. That’s what the ‘Save’ feature is for.”
Based on Chapter 5, Game Architecture and Design, by Rollings and Morris
76. Specific Example -
The Save Game Problem (1 of 2)
• Should be used only so players can go back to
their Real Lives™ in between games
– Or maybe to allow player to fully see folly of
actions, for exploratory and dabbling
• Don’t design game around need to save
– Has become norm for many games, but too bad
– Ex: murderous level can only get by trying all
combat options
• Beginner player should be able to reason and come
up with answer
– Challenges get tougher (more sophisticated
reasoning) as player and game progress, so appeals
to more advanced player
– But not trial and error
Based on Chapter 5, Game Architecture and Design, by Rollings and Morris
78. Gameplay/Gameplay Balance
• Challenges when balancing aspects of gameplay?
– Want variety of interesting choices, rather than
single, dominant choice
– Best choices depend upon choices of other players
(or on AI)
– Not easy to see how frequently different choices
will be worth making, but need to know to balance
game
• Sounds like catch-22? Can use simple concepts to
make first guess
– Then lots of play testing to fine tune!
Based on Chapter 5, Game Architecture and Design, by Rollings and Morris
79. Component Balance
• Two levels to balancing: component and attribute
– Component balance deals with relative values (ex: cost
and strength)
– Attribute involves interaction of abilities (ex: speed
versus hit points)
– Talk about component first, attribute later
• Establish the value of each game choice
• For game balance, each choice must be reducible to simple
value and factors must even out
• Ex: Pirate game
– Dreadnoughts > Galleons > Brigantines
– All have identical functions
– If Dreadnoughts 2x powerful, then (for balance) Galleons
should take ½ time to spawn
Based on Chapter 5, Game Architecture and Design, by Rollings and Morris
80. What if Not Easily Reducible?
• Ex: Starcraft
– Mutalisks fly over any terrain, but cannot fight
other fliers
– Wraiths are not as tough, but can attack other
fliers
– Observers can see enemy, but not fight
There is no expression for values since different
things!
• Ex: Pirate game
– Dreadnoughts slowest, Brigantines fastest
Interesting from gameplay, but what about
balance?
Based on Chapter 5, Game Architecture and Design, by Rollings and Morris
81. Attribute Balance
• Involves not the relative values, but the way the
choices interact
– Ex: How important is ship speed relative to combat
strength?
• Envision as a set, where relative values based on one
factor only:
– Speed: Brigantines > Galleons > Dreadnoughts
– Tuffness: Dreadnoughts > Galleons > Brigantines
– Range: …
• Can then combine to get average set combining all
factors
• Then, adjust component values (often, through play
testing) so all units are useful
Based on Chapter 5, Game Architecture and Design, by Rollings and Morris
82. Component versus Attribute
Balance
• Mnemonic to remember:
– Component choices are about artifacts
• Ex: “Hmm. Should I use the ion cannon or laser?”
– Attribute choices are more abstract regarding use:
• Ex: “I should sneak past troll or take extra health”
• Attribute balance is harder (set of all problems)
• But if can get approximate picture of better
strategies, can tweak component costs to get
game balance
Based on Chapter 5, Game Architecture and Design, by Rollings and Morris
83. Intransitive Game Mechanics (1 of 5)
• Payoff, match your choice with opponent
• Suppose I always picked rock. Then opponent
would notice and pick paper. Then I would start to
always pick scissors, then…
– spiral to center of triangle where all options equal
– only break even, like thermodynamics
Rock Paper Scissors
Rock 0 -1 +1
Paper +1 0 -1
Scissors -1 +1 0
Based on Chapter 5, Game Architecture and Design, by Rollings and Morris
84. Intransitive Game Mechanics (2 of 5)
• Suppose scissors costs most, rock costs
least
– May use rock more often, scissors less
– But wait, that would mean paper less useful,
too… what is optimum choice now?
• Suppose scissors costs 3 ki, paper costs 2
ki, rock costs 1 ki and hit does 5 ki damage
Rock Paper Scissors
Rock 0 -4 +7
Paper +4 0 -4
Scissors -7 +4 0
Ex: I choose scissors, you choose rock. Ki diff is –2.
Plus damage is –5, so –7 total.
85. Intransitive Game Mechanics (3 of 5)
• Say payoff is R, P, S and frequency r, p, s
– Want to know how often used (r, p, s)
• Net payoff R is (0 x r) + (-4 x p) + (7 x s)
1) R = -4p + 7s
2) P = 4r – 4s
3) S = -7r + 4p
• Sum must be zero (zero sum game, whatever one
player gains other loses. Both cannot have net
gain.)
– R + P + S = 0
• All costs must be equal else would favor
(remember, triangle example)
– R = P = S
Based on Chapter 5, Game Architecture and Design, by Rollings and Morris
86. Intransitive Game Mechanics (4 of 5)
• Solve: (3 equations in 3 unknowns)
– (eq1) -4p + 7s = 4r – 4s (eq2)
11s = 4r + 4p s = (4r+4p) / 11
– (eq2) 0 = 4r – 4(4r+4p)/11
0 = 44r – 16r - 16p
0 = 28r - 16p p = (7/4)r
– (eq3) 0 = -4(7/4)r + 7s
0 = 7r + 7s
r = s
• Ratio r:p:s = 1 : 1.75 : 1
– Rock and Scissors used 27%, Paper about 46%
– Probably not what expected. Often result … if one
option more expensive, others are most affected
Based on Chapter 5, Game Architecture and Design, by Rollings and Morris
87. Intransitive Game Mechanics (5 of 5)
• Can use technique to adjust costs
– Ex: if it turns out “too many” tanks relative to infantry
• Enhance to more choices.
– Ex: could do combination moves.
• Rock + Scissors + Scissors = Garden Shears
• Could be countered with Paper Weight
• Strategy becomes complicated
• (Can also use to justify spending more artistic assets on
paper!)
• Fine, all is balanced. Players must avoid predictability
because clever opponent will exploit.
– But that is barely above where have only 1 choice!
• To balance so interesting, must have attribute factors that
interact (remember, the Battle of Hastings)
Based on Chapter 5, Game Architecture and Design, by Rollings and Morris
88. Other Intransitive Relationships
• Can extend RPS? Sure (otherwise not useful)
• More than 3 options Table 5.3 and Case Study
5.5
• Less regular are 4 options Table 5.4
• Figure 5.7 discusses another 4-way relationship
– Infantry dominated
– But, looking further, infantry only one that doesn’t
have to move
• Can hold territory! (In game that needs that)
– Ex: In AoE, could “teleport” supplies by building
base. Didn’t need to hold territory. Infantry
useless. Even making them cost less doesn’t
(expansion pack). Still great game, but didn’t need.
Based on Chapter 5, Game Architecture and Design, by Rollings and Morris
89. Combinatorial Explosions
• How many attributes should there be to make
interesting?
– Too few? Then becomes trivial (Ex: in Hastings, only
way to change power base is to put infantry on hill)
– Too many? Then too hard to have skilled play
• Rule of thumb: N factors that could modify core
mechanics, and each boolean (hill or not, rain or
not …) 2N
possible combinations … explodes
rapidly
– Err on the side of caution
“In Populous (EA god-game), should have lots of characters or
half-dozen? Noticed would be easier to understand game
experience with few, versatile units rather than many
specific ones.
Richard Leinfellner, Exec in charge of Bullfrog
Based on Chapter 5, Game Architecture and Design, by Rollings and Morris
90. Design Scalability
• Intransitive designs are inflexible
– If have 5 way relationship and remove one, will have
dominated strategy
– Ex: RPS and remove R … always choose S
• If project lead says behind schedule, so don’t
include 5th
orc type
Elegant design falls like a house of cards
• But is relatively easy to add components
– Doesn’t have to be symmetrical, can be redundant or
useful in only a few cases
• Ex: scout, or special spell
• Lesson, if you are going to scale, scale up not down
Based on Chapter 5, Game Architecture and Design, by Rollings and Morris
91. A Game Balance Checklist (1 of 3)
• Player-Player – ensures game is fair.
Increasingly important as multiplayer
increases. Symmetry works for this, but
asymmetry may be needed or more
appealing (try “just broken”). Make sure
any asymmetry doesn’t magnify imbalance
as game progresses.
• Golden rule: a player should never be put in
an unwinnable situation through no fault of
their own
Based on Chapter 5, Game Architecture and Design, by Rollings and Morris
92. A Game Balance Checklist (2 of 3)
• Player-Game – ensures player never
becomes frustrated. Continually brings
player back for more. Interface should not
present obstacles. Small rewards are
needed to guide player (fancy animation or
new powers). Best rewards widen options.
• Golden rule: The game should be fun to
learn as well as to play, and it should be
more fun the more you master it
Based on Chapter 5, Game Architecture and Design, by Rollings and Morris
93. A Game Balance Checklist (3 of 3)
• Gameplay-Gameplay – makes sure no element
redundant or useless. Can do briefly by making
factor table for each attribute (fire, range …)
Make sure each best at something. RPS ensures
each component dynamically best rather than
statically so. Oblige player to alter tactics. Don’t
have to have every component equally useful. But
cost, availability and ease of use should reflect
value. Get right through playtesting.
• Golden rule: all options in game must be worth
using sometime, net cost of each option must be on
par with payoff
Based on Chapter 5, Game Architecture and Design, by Rollings and Morris
94. Look and Feel
• (Me: consider skipping this whole section)
• Create a sense of alternate reality –
Immersion
• Ambience
• Interface
• Storytelling
Based on Chapter 6, Game Architecture and Design, by Rollings and Morris
95. Ambience
• Everything that contributes to innate look and
feel of game
– Not just spiffy graphics - GLFOPS and trilinear
filtering
– Rather, how graphics are used
• Two fighters on bare stage. Fine. How about
dirty street, realistic crowd hooting and hollering.
Dark skies…
– Ex: “Fiery hell” when battling boss in Battlegrounds
• Ambience is about providing background for story
• Broadly – Sound, Vision, Touch
Based on Chapter 6, Game Architecture and Design, by Rollings and Morris
96. Sound
• Wistful guitar in Diablo
• Ethnic rhythms in AoE
• Stirring call to arms in Warcraft
• Whimsical in Q’Bicles
• Best does ambience plus gameplay
– Ex: Thief
• “Come out taffer”, looking for you
• “Just a rat”, you are safe
– Ex: LOTR
• “Stirring” music when level nearly over (but can still die!)
Based on Chapter 6, Game Architecture and Design, by Rollings and Morris
97. Vision
• The "look" of the game
• Concept art
• Broad strokes, not pixel
finished detail
• Rough sketches of characters
or settings
Based on Chapter 6, Game Architecture and Design, by Rollings and Morris
- Paolo Piselli
99. Touch
• Not really “touch”, but physicality of games look and
feel – handling of game
– Ex: early animation characters did not move right –
Disney pioneered with physical attributes that felt
right, moved with weight
• Contrast
– Ex: comic-book acrobatics in Smash Bros
– Ex: bouncing vehicles in Mario Kart
– Ex: realistic crashes in Mid-town Madness
– Ex: super-players in Lego Soccer
– Ex: realism in Madden (actually, guys 1.5 times faster)
Based on Chapter 6, Game Architecture and Design, by Rollings and Morris
100. Interface
• Ideal is transparent
– Ex: LOTR BfME novel way when click
expands with choices
– Ex: Status can be in formation or
appearance (not health hit-points, say)
• Doesn’t have to be invisible
– Ex: racing game expects dash
– Ex: flight sim interface can look like cockpit
– Ex: less is more (small square more annoying
than framing with interface)
• Can enhance look and feel
Based on Chapter 6, Game Architecture and Design, by Rollings and Morris
101. Storytelling
• No need of story? After all, supposed to be
interactive.
– “If you want to tell a story, write a book.”
– Bah. Consider “choose your own adventure”
• Ex: Doom – two factions
1) Strong setting and backstory enhance game
2) “Story? We don’t need no stinking story!”
• Action takes care of itself
• Interactive can help user create story
– Ex: Half-life
• Stronger – want to suspend disbelief of user but
need to make them want to suspend
– Ex: Starwars merely some sword fights and vehicle
chases. Need to know who Luke is, why he’s in the
spaceship. Why the battle …
Based on Chapter 6, Game Architecture and Design, by Rollings and Morris
102. Toolbox of Storytelling Techniques
• Best not chunks of action with static
facts
• Details revealed to audience – let them
figure it out
• Get emotional involvement from audience
• Storytellers knew tricks for creating good
stories long before Shakespeare – Game
Designers should employ
– Obstacles, Plot Points, Foreshadowing …
– (More next)
Based on Chapter 6, Game Architecture and Design, by Rollings and Morris
103. Obstacles
• Old man runs to hero in inn. Says “Vampire
on hill. You have to kill it.”
– Poor
• Old man enters inn. Avoids hero.
Purchases crucifix from another. Mumbles
“you better have one if you are in these
parts.”
– Not great, but better. Has obstacle
• Viewer must find out himself/herself
• “Tricked” into level of acceptance not
obtained if just told, too artificial
Based on Chapter 6, Game Architecture and Design, by Rollings and Morris
104. Foreshadowing
• A story depicts the intrusion of the world
on status quo
– Ex: AoE – settlement grows to large city
– Ex: Total Recall – construction worker spy
• Foreshadowing occurs early, before
intrusion, hints at what is to come
– Ex: AoE – small bandits come, fought off
– Ex: Total Recall – dream of spy
Based on Chapter 6, Game Architecture and Design, by Rollings and Morris
105. Personalization
• Novice author – Ex: save the world, because big
– But not compelling, so only you can save it
– Still weak
• Need to add person reason so audience cares
– Ex: you have two hours to save the world versus you
have two hours to find your niece lost at sunset
– Ex: Luke told must save galaxy. Why? Drawn in by
personal (Princess Leia)
• Careful not to make personal hook in backstory –
might skip
Based on Chapter 6, Game Architecture and Design, by Rollings and Morris
106. Resistance
• Back of mind saying “it isn’t true”
– Need to pull them along
• Ex: Bruce Willis, drinking at dingy strip
club. Two suits say “you must save
president from terrorist.” Does he jump
up and get to work? No. Snarls “I’m
retired.” Takes another drink.
– We want him to change his mind. Rooting
for him before main character does.
Based on Chapter 6, Game Architecture and Design, by Rollings and Morris
107. Plot Points (1 of 2)
• Importance of confounding expectations
– Ex: Gandalf on quest to Mount Doom. Boring if that
is exactly what happens
• Gets killed early on (and comes back), not expected
• Adventure games benefit most, but can do for
other games, too
• Aristotle – reversal, discovery, calamity
– Ex: trying to save kid, causing her death (reversal)
– Ex: finding Swiss account number on victim
(discovery)
– Ex: bomb going off, killing hero (calamity)
Based on Chapter 6, Game Architecture and Design, by Rollings and Morris
108. Plot Points (2 of 2)
• Games, too.
– Ex: strategy game – find cliff so army built up won’t
work (reversal)
– Ex: tunnel for small commando force (discovery)
• Whammo every 10 minutes, turn story in different
direction
– Big ones (“Luke, I am your father”) divide into levels
or acts
• Movies - setup, conflict, resolution
– But games whole season (40 hours), not one movie
– Best if can integrate in game without cut-scenes
• Early plot points deepen mystery, later clear it up
(not always completely)
• Overarching structure, hierarchical in plot points
Based on Chapter 6, Game Architecture and Design, by Rollings and Morris
109. Suspense
• Ex: Unbeatable foe (Gorgon, only beat by
lure to trap). With “save game” let hero
try. After 9 times, try something else.
– Death of lead character destroys illusion
• Instead, provide clues, suspense. Bodies,
rotting, see NPC get eaten. Hear sounds.
Can see gorgon survive rock crash.
Based on Chapter 6, Game Architecture and Design, by Rollings and Morris
110. Dialog
• One picture worth a thousand words
– Don’t have needless dialog when visual will do
• Good dialog serves more than one purpose
– Ex: telling about bomb. “How long?” Plenty of time
… smoke cigarette, call mom … don’t read War and
Peace. Reminds of mortality.
• Don’t tell what know, but also reveal
– “Do you expect me to talk?”
– “No, Mr. Bond, I expect you to die”
• Surprise
Based on Chapter 6, Game Architecture and Design, by Rollings and Morris
111. Resolution
• Should be:
– Hard won – no reward is satisfying if too easy (most
computer games not this)
– Not obvious – don’t want ending one been seeing for
10 hours (yet should still make sense looking back)
– Satisfying – usually morally (hero wins) but could be
aesthetically (tragedy)
– Consistent – with character, style development
– Achieve closure – resolve story
• Many examples of stories/games where above fails
– Diablo 2 – defeat Diablo … then 60 seconds to end.
– Might and Magic 2 – long struggle, mystery. Very
end, control panel … 15 minutes to decode
‘’Fourscore and seven years …” Solved it, asteroid
missed, thank you and go home
– Ex: A Christmas Story – decoder ring drink Ovaltine
Based on Chapter 6, Game Architecture and Design, by Rollings and Morris
112. Change
• Stories set in interesting times
– No “Sir Gawain shops for bread.” Rather,
“marries hag, one week until green knight
chops head off”
– Sometimes, return to normal
• Inner change is often point of story
– No “Frodo lives in Shire with friends”,
rather “learns of evil, innocence to self-
knowledge”
Based on Chapter 6, Game Architecture and Design, by Rollings and Morris
