Single-prompt playable real-time 3D game

Build a playable real-time 3D game from one prompt. Define a compact core mechanic, a clear objective and short story, then generate the scene, characters, props, feedback and restart state so the result can be played immediately.

Prompt optimization tips

1

Specify editability

State which objects must remain separate, named and editable; otherwise a visually convincing shell may still be unusable.

2

Close the test loop

Ask the model to run the scene, inspect visible failures and repeat until concrete frame-rate, interaction and layout checks pass.

3

Stage long builds

For large worlds, split the work into districts, assemblies or milestones and approve each section before expanding scope.

Imagine It. Shape It.
