Developer chrisfirst built Fallout: New York — a full Fallout game playable in the browser, created with Claude Opus 5.5: quests, dialogue trees, V.A.T.S., and a working Pip-Boy.

The striking part: zero texture and zero sound files — every building, weapon, face, and sound is generated by code. Commenters called it proof that 'everything can be simulated' and asked how it was built.
