Four people. One game.
Not enough hours.
How two open-source projects let a small team talk to
their tools instead of clicking through them.

Everybody here does two jobs
Mei
Designer
…and the person who tunes
every number
Ken
Artist
…and the person who imports
400 files by hand
Ana
Programmer
…and the only one who knows
how the build works
Sam
Producer
…and everything nobody else
has time for
TH E P L AN Ship one small game in six months. They have the skill. They do not have the hours.

The week they actually have
Not a statistic. A composite week, told as a story.
Monday Ken imports art Same settings, 400 files, one at a time
Tuesday Mei waits for a scene She cannot tune the game until it exists
Wednesday Ana fixes the build Nobody else can, so nothing else moves
Thursday The phone build is slow Found late, because nobody checks until it hurts
Friday They design the game The one day that matters. The first to get eaten.
Their skill was never the bottleneck. Repetition, waiting and late surprises were.

What if Monday were one sentence?
H O W I T WO R K S TO D AY

Little Ghost Starts Running
I think the Pac-Man game is too boring. I want to
replace the enemies in Pac-Man with ghosts. I already
have the Asset ready, but I don't know how to do the
replacement. Can you follow best practices and help
me swap them? My ghost is in GhostCharacter_Free

Real Customer Feedback
Using Kiro Unity Accelerator with Photon Engine to develop
multiplayer online games. A networking framework that originally
took three weeks to learn was completed in just a day and a half
with Kiro.
Non-engineering team members can operate Unreal Blueprint through
natural language, bypassing the C++ learning curve. Engine operations
that used to take newcomers months to master can now be
independently delivered within days.
At the "Garena × Rayark Game Jam" in June this year, co-hosted by Garena and
Rayark Games with technical support from AWS, participants experienced Kiro
firsthand. Over three days, 120 developers in 20 teams faced tight deadlines and
intense pressure — the ultimate stress test that exposes every possible issue.

One expert is not a studio
Chapter one gave one expert her week back. But three other team members are still waiting.
DESIGNER ASKS
"Is this even the right
game to build?"
A Unity expert has no opinion
on game design.
ARTIST ASKS
"Who makes the art
and the music?"
Those live in other tools
entirely.
ANALYST ASKS
"Are the numbers and
the law right?"
Payout maths and ratings are
their own trades.
AND THE HONEST ONE
"Should we even use
Unity?"
You cannot ask a Unity expert
that. It will always say yes.
A deep specialist cannot make the calls that span the whole project. You need someone above them.

Please help me develop a first-person shooter game in Unity with a modern military style.
The player has three weapons: pistol, rifle, and grenade.
Enemies are terrorists, with two types: infantry and snipers.
The level is set in an abandoned warehouse where all enemies must be cleared.
Include a crosshair UI, health bar, and ammo display.

What you just saw isn't "AI writing code" —
it's a production line with specifications,
handoffs, reviews, and validation.
Specifications: shooter-expert Handoffs: Contract + Manifest Reviews: Lead review gates Validation: Simulation reports

The AI team executes; you make the decisions
This framework doesn't hand the game to AI — it hands execution to AI and keeps the steering wheel with you.
What the AI team handles for you
Spec expansion, task decomposition, cross-team handoffs
(Contract auto-linking)
Texturing, modeling, scene assembly, testing, and other
execution work
Numerical values are first validated through simulation
GDD and style guides are auto-loaded — every Agent follows the
rules
You are still the director
The Producer plans before starting — execution only begins
after your approval
Creative direction and the final call on "is it fun"
Final authority on review gates; full git history is always auditable
You define the GDD and style guide — that's the soul of your
game

My personal take:
AI won‘t replace game developers,
but developers who can orchestrate AI teams
will be able to build games that were
previously impossible.

Thank you for
listening
