Needs Assessment
1.1 Brief Description of Motivation
As contemporary society becomes more social media driven and individuals have the
ability to easily communicate and share topics of interest to them, online communities
related to trading card games are becoming ubiquitous. A trading card game is also
commonly referred to as a collectible card game, customizable card game or CCG.
Essentially a trading card game (TCG) combines the collectability of trading cards with
strategic play. Since a match in TCGs require a minimum of two players to engage in a
duel, online communities presented a place where users can congregate to purchase and
trade cards, find opponents and tournaments, exchanging deck ideas, market information,
and the metagame related to TCGs.
There are two demographics for trading card gamers: the younger and older generation.
The younger group composes of children between the age of six and fourthteen, while the
latter consists of children and adults ages sixteen and older. Due to my interest in creating a
social network for trading card gamers, the demographics of TCG message boards are
paramount in understanding what card games should Gamer’s Log focus and how active are
gamers’ activities on forums. A study conducted in a paper titled “Trading Card Game
Industry White Paper: From the T to the C to the G”, collected information from fourteen
English based online message boards in May 2009 where 1,138,510 players collectively
contributed 29, 396, 134 posts. From this data the report concluded that market percentage
of TCGs discussed online is over 51% for Yu-Gi-Oh!, followed by Pokémon 35% and 7.7%
for Magic: The Gathering. However, both Yu-Gi-Oh and Magic: The Gathering is
immensely competitive with hosting regular national and regional tournaments every month.
Due to trading card games popularity, websites emerged to cater to players thirst for
wanting to purchase cards and exchanging strategies. Therefore, I believe since Yu-Gi-Oh!
and Magic constantly host events that attract hundreds of players, there is more of a need to
properly prepare for tournaments which require market information and exchange of deck
strategies. Contemporary trading card game websites, such as TrollAndToad.com and Alter
Reality Games, primary focus is selling hobby items, promoting tournaments, allowing
professional card gamers to write articles and permitting gamers to exchange information
through forums and/or commenting to articles, however, this is a secondary service.
Although message boards are a common means of communication, it is also very limited. If
no other users’ comment on a topic, then the forum remains idle and soon closed by
administrators. Consequently, a player who was seeking advice or assistance does not
receive it.

4. 3
Websites that permit professional gamers to write articles will not allow novice or
intermediate skilled gamers to post articles on their websites. Normally gamers who post on
these websites are paid and sponsor by websites. While sites such as Pojo.com, allow any
user to submit deck ideas, permit volunteer users to act as feature writers, offer card of the
day reviews and messages boards. With ever changing technology that enables for
instantaneous response, Pojo.com has not embraced it, therefore, users complain about
message boards. However, as mentioned earlier, forums limitations lie in gamers not
commenting to a user’s post. For gamers who want to discuss information, they use
platforms such as Tumblr, BlogSpot, Facebook, and other social networks.
There is not a website dedicated primarily to building a network of gamers, thus I
purpose the creation of a trading card gamer social network that acts as a profile and
communication platform. A profile, a digital resume, will enable users to share TCGs pet
peeves and fetishes for games they play. Our communication platform is a blogging system
where card gamers can exchange deck ideas, market information, the metagame and
opinions about collectible card games. Our initial market is for Yu-Gi-Oh! and Magic: The
Gathering players.
As a result, my two primary motivators for creating Gamer’s Log are:
1. There is not a dedicated social network service for trading card gamers.
2. Strip barriers or privilege away from gamers who want to share knowledge or
express opinions about trading card games.
3. Allow users to digitally record their accomplishments and TCG information.
1.2 Environment or Scenario
The environment is a real world application of a social network database for individuals that
play trading card games, primarily Yu-Gi-Oh! and Magic: The Gathering.
1.3 Users
The users are trading card gamers that play either or both Yu-Gi-Oh and Magic: The
Gathering.
1.4Data/Information Needs
The multivalued attributes for Log’s Hobby Category is Trading Card Game. The
multivalued attribute for Hobbies are TCGs: Yu-Gi-Oh!, Magic: The Gathering, Cardfight!
Vanguard, Pokémon, Dragon Ball Z, Naruto, World of Warcraft, Kaijudo, Legend of the
Five Rings, and Vampire: The Eternal Struggle.
1.5 “Mini-World” Description

A LOG is an article also refereed to on the web as a web log. The LOG attributes are

User Id (primary identifier), User Id, and Fanned Id.
A USER PROFILE is personal information of a user that related to either both or one of the

Peeves and Yugioh Fetishes. MAGIC THE GATHERING PROFILE consists of Magic Pet
