Two prompts, $30 in tokens: opus 5.5 builds a playable zoo tycoon game
jacob_posel · x · 2026-09-26
Developer Sean Frank used two prompts on opus 5.5 to generate a fully playable medieval zoo tycoon game: a working economy with pricing for everything, attraction building, mythical beasts, a full terrain builder (streets, fences, shops), plus staff hiring and feeding to keep beasts alive. He notes the quality would have sold as a paid iPhone app two years ago — and it cost about $30 in tokens. The game is hosted and playable on HQ, which turns Claude projects into multiplayer experiences.
