Another interesting experiment by @atomic_chat_hq （a desktop app that runs LLMs locally）.

Muse Spark 1.1 rendered 3D arcade games that play themselves for $0.026， significantly lower than Gemini 3.6 Flash.

Both models got one brief， 3 tabletop games that run themselves with no player input. The code had to drive every shot， since nobody touches the controls.

Muse Spark 1.1 spent 31.3K tokens and finished the full set for $0.026. Gemini 3.6 came in leaner on tokens at 28.8K， yet its run cost $0.073.

For this kind of 3D arcade games， the real-time physics， a scattering rack or a bouncing puck， all these are genuinely hard to get right.
