One-shotting a Raccoon Heist game using Claude Fable 5
ai
Claude Fable 5 built a complete, playable 3D video game from a 2022 tweet, according to Simon Willison's Weblog. Given only concept art and a game premise called Raccoon Heist, the AI generated textures, programmed a title screen, and developed guard dogs with scent-tracking behavior — all without further input. Willison provided a single prompt and stepped back; Fable handled the rest autonomously.
