Simon Willison: October 2026 is the inflection point for vibe game development
vista8 · x · 2026-10-29
vista8 relays Simon Willison's latest post. Willison argues that just as November 2025 (Opus 4.5 / GPT-5.1) was the inflection point for vibe coding, October 2026 is the inflection point for vibe gaming — Claude Opus 5.5 makes big leaps in 3D modeling, music generation, and game design.
Key points:
- Models could long produce things that "look like games"; the hard part was making one that's actually fun. Game design — a compelling gameplay loop and satisfying learning curve — is a deep craft, and Willison didn't think models could do it
- He told Opus 5.5 to "Make it a LOT more fun"... and it did. In recent weeks he vibe coded (no code reading at all) four games he genuinely enjoyed: Tree Appreciator, Emberwick, Battle Drones, Pumpkin Farmer
- At Foo Camp he met several people with the same experience: building games that play well is shockingly easy now; the new bottleneck is coming up with concepts
- vista8 adds: DHH also says Opus 4.5 was what stunned him; GPT-6 Astra can make games but is less fun than Opus 5.5, likely catching up by year-end
