This shelf has about 55 games, 3D scenes and head-to-head game builds. The steadiest thread is Dilmer's Mini Golf project: he used Muse Code with the Unity CLI to run tests, port the game to other platforms and bring it to VR, then added hand tracking in under an hour with Muse Spark 1.3.
Plenty are one-shot tests. Chris got a working Flappy Bird clone in a couple of minutes, Tornado guy got 3D table tennis with sound, and Matt Deitke turned a photo of a Sudoku board into a playable game. thehype runs recurring bake-offs where Muse Spark and other models build Three.js dioramas, paintings and Star Wars worlds from the same prompt.
Some builds go further. Mostly Borrowed Ideas made Hindsight Capital, an investing game built on real financials of anonymized companies. Sparkade is a Raspberry Pi arcade cabinet that generates SNES-style games. When-Agents-Rule drops Muse Glimmer, Qwen and Gemma on one island for a 90-minute strategy game.
