- A user says they tried the Claude Opus 5 “one-shot playable game” prompt for their son’s birthday and got a game running on a TV-sized screen after a 21-hour run on a paid plan.
- They contrast it with an earlier attempt on Opus 4.6, which reportedly took much more effort and produced a bad result.
- The post frames the demo as evidence that AI-made games are moving from gimmick territory toward something genuinely impressive and personalized.
