Battle Drones - a vibe coded RTS with audio-based multiplayer

Simon Willison built a full RTS game via vibe coding with Claude Code across 321 commits

“I'm somewhat embarrassed to admit that I got there by telling Claude to "Make it a LOT more fun"”

Simon Willison iterated a Command & Conquer-style RTS to a playable state using Claude Code as the primary coding agent, accumulating 321 commits across 12 major versions. The project showcases vibe coding's practical ceiling—3D models, fog of war, random map generation, and audio-based multiplayer—while highlighting that natural-language steering ('Make it a LOT more fun') drove key quality leaps. It's a concrete data point on AI-assisted game development but lacks broader industry or policy implications.
