The day's top r/ClaudeAI post (1,000 upvotes) is a 24-hour autonomous Opus 5 run on an open-world city game, with the model choosing districts, roads, buildings, pedestrians, vehicles, and weather. A companion at 108 upvotes documents a 3D moon rover survey game: one WebGL2 context, vendored three.js, ~6,300 lines of JS, no build step, nothing to npm install, terrain that persists every rut the wheels cut. The metric moved from quality-of-one-generation to hours-without-intervention.
