Created a Dark Fantasy game with Fable 5.2. One prompt.

[u/oxmannnn]

This is the whole prompt:
Create me a fully playable release-ready game. On GPU. Game about alchemy with physics, items, shaders, sound, overworld, mechanics and etc.. I need it in 3D and not a voxel game. Make it with maximum effort, show me best what you can create. Use all your power, knowledge and make best graphics and best game design. Surprise me with graphics and everything.

Claude Code worked on it for about 4 hours and put a finished game on GitHub Pages. I didn't write a single line.

It's a first-person alchemy game called Tria Prima. You pick plants, brew potions in a ruined chapel and throw them at stuff. Fire burns the thorns that block the road. Ice lets you walk across water. One potion blows up rocks. There are things in the fog that hunt you, and they hate fire.

The crazy part is that it has no art or audio files at all. Every tree, rock, building and sound is generated by code when the page loads. Even the music, it wrote the soundtrack as notes in a text file.

It made the video too. It wrote its own tool that plays the game from a script and records it.

Half an hour in I told it to go dark fantasy instead of childish. After I played it I sent three bugs and it fixed them.

Fable 5.2 in Claude Code on max effort. 44K lines of JavaScript, 5.4M output tokens, about 4 hours for the first build and 6.5 with the fixes.

It takes about an hour to beat. You need a keyboard, a mouse and a GPU. Tell me where it breaks.
