Fallout: New York, with zero texture files
Chris First built Fallout: New York in the browser with Claude Opus 5.5: quests, dialogue trees, V.A.T.S. and a Pip-Boy. No texture files, no sound files. Buildings, weapons, faces and audio come from code.
The feature list is a genre checklist, which is why it is bold. Chris First's Fallout: New York, built with Claude Opus 5.5, runs in the browser and claims quests, dialogue trees, V.A.T.S. and a working Pip-Boy. Then the constraint: zero texture files, zero sound files. Buildings, weapons, faces and sound are generated by code.
Fallout's identity is interface as much as wasteland. A Pip-Boy that is only a picture fails the fantasy. A Pip-Boy you operate, next to dialogue that branches, is the fantasy — and doing it without a texture folder means the UI, the characters and the guns had to be drawn by the same program that wrote the quests.
It is a fan game, and it wears the name openly. The thing to test is the checklist, item by item, because each item is a system and not a screenshot.
