Your brief
Describe the game, original characters, world, target platform, and multiplayer needs.
YOUR CODING AGENT. YOUR GAME.
Make the game
you can’t stop
thinking about.
Open Game gives coding agents a structured path from your original idea to editable engine files, playable builds, and the next iteration.

GET STARTED
One install.
Your agent’s workflow.
Install the CLI from GitHub, check your local tools, and open the Blueprint Studio. The MCP server connects the same project tools to your coding agent.
BEFORE YOU START
Git · Node.js 20 or newer · a coding agent. Game engines are optional until you build a project that needs one.

THE WORKFLOW
From a brief to a
build you can inspect.
Open Game is the toolbelt and production guide. Your connected coding LLM does the game-specific design and implementation.
OPEN GAME / CREATOR-TO-BUILD FLOW
Studio + skill
Export a blueprint or build brief. The Open Game Creator skill gives your agent a full implementation contract.
Agent + tools
The LLM edits real project files using the shared core, CLI, and MCP operations.
Build + play
Inspect the engine, build, run, fix observed issues, record evidence, and package supported outputs.
ENGINE TARGETSGodot·Unity·UnrealInitial adapters; each operation depends on the installed engine and configured project.
THE TOOLKIT
One workflow.
Useful entry points.
Blueprint Studio
Capture a game vision and export a structured blueprint or agent-ready brief.
Open Studio ↗Open Game Creator skill
Guide an agent through the real project, connected systems, implementation, build, play, and continuation record.
Read the skill ↗CLI + MCP
Inspect tools, create project handoffs, plan systems, track obligations, run supported engine operations, and package exports.
Connect MCP ↗Build adapters
Use available project integrations for engine builds and scenarios. Check requirements and limits before selecting a target.
View support levels ↗ CONNECT YOUR AGENT
Bring the workflow
to your coding agent.
Run the local MCP server over stdio and add it to the MCP configuration supported by your agent. Set a workspace folder where projects may be created, then restart the agent.

OPEN DEVELOPMENT
Built by creators.
Improved in public.
Follow releases, inspect the source, report problems, and help shape the tools. Open Game is an independent community project.
FIRST TAGGED RELEASE · v0.2.0

GUIDES + FAQ
Clear about what
it does today.
Start with the docs, check the limits, and use the tools that fit your environment.
Does Open Game generate any finished game from one prompt?
No. A creator's brief starts an end-to-end coding-agent task. The connected LLM implements the game, and scope, quality, assets, and builds depend on that agent and its environment.
Is the LLM included in this package?
No. Open Game supplies the agent workflow and project tools. Use your own coding agent and configure its model/provider separately.
Which engines can I use?
The project schema is engine-neutral and current adapters include initial Godot, Unity, and Unreal operations. Build support is partial and depends on the engine, export tools, presets, and project configuration.
Does Open Game provide online multiplayer hosting?
No. The toolkit can represent multiplayer requirements and includes a bounded example server. It does not provision production matchmaking, identity, cloud saves, or hosting.
Can it make a copyright-safe clone?
Open Game supports original projects inspired by broad genres. No scan or workflow can promise legal safety; use original or properly licensed material.
How do I contribute or get support?
Read the contribution notes in the repository README, open an issue, and include your environment and exact command output where relevant.
