Simon Willison published Battle Drones, a browser-based Command & Conquer-style RTS built over 12 major iterations and 321 commits from coding agents (mainly Claude Code), playable on mobile and desktop. It ships 9 buildings, 7 ground vehicles, 6 aerial vehicles and 3 infantry units as 3D models, six maps across five biomes plus a random map generator, fog of war, Skirmish and Last Stand modes, AI personalities, an AI-vs-AI spectator mode, and an Agent vs. Agent mode where two LLMs play each other. The headline trick is multiplayer between two nearby devices that synchronise game state over audio messages, an extension of his earlier Chirp Pong experiment.

Why: Two things worth copying: he credits the jump from 'technically working' to fun to a single qualitative prompt ('Make it a LOT more fun') rather than more features — try that before adding scope to your own prototype. And the audio-channel multiplayer means two phones in microphone range can sync state with no server, no pairing flow, and no backend cost, which is a usable pattern for demos and local co-op where you cannot justify infrastructure. The 321 agent commits across 12 iterations is also a concrete datapoint on how much review surface agent-driven development creates.
