Developer prasenx showed off Valley Ride, a 3D horse-riding game built in two days by Claude Opus 5.5 and Fable 5.2, now playable free in the browser — declaring "video games are about to change forever".

The game is a relaxing valley ride: follow a trail past four lanterns to reach a campfire on the summit at sunset, with no score or fail state. You can walk, trot or gallop past wild horses, ford a river, jump logs, switch between first-person and chase camera, and use photo mode. It runs on WebGPU in desktop Chrome/Edge and was built with Claude Code and Blender.
