Game Creation Studio
Start with the choice players will make. Game Creation Studio helps you shape a playable idea, test a prototype or build, and prepare a tabletop session around the people at your table.

Find the choice players want to make again.
What can you do with it?
- 01
Turn an idea into a playable slice
Find the core loop, cut the scope to one complete run and plan the first test before choosing content or an engine.
- 02
Design rules people can play
Shape systems, balance, board and card rules, controls and onboarding, then learn from real playtests.
- 03
Prepare and run tabletop sessions
Plan scenes and NPCs, get compact help during live play, teach rules quickly, keep the table safe and write the recap afterward.
Start with one idea or session.
Share your game idea or project, platform, audience and the decision you need to make. For tabletop play, include the system, session plan and your table’s needs. Name a skill or let the assistant choose.
Help me find the core loop in this game idea: [idea]. The audience is [audience] on [platform]. Name the player's repeated choice, the feedback they get and what changes, then scope a small prototype I could test with players this weekend.
Bring: A game idea, the audience and the platform. Expect: A core loop, a small prototype scope and a first test.

Uploading a ZIP into an ordinary web chat does not install the plugin.
Design, playtest and tabletop work need only your AI app. Asset production and build diagnosis use a separately installed game-dev command-line tool, and engine work uses your game's own tools. Check the requirements.
