This is the future of gaming! Everyone turning a prompt into the dream game they’ve always wanted to play. Opus 5.5 helped me build a GTA 2–style game—and now I can’t stop playing it 😂🔥 Grok made the cutscene. GPT Astra modeled the Tesla after Opus declined. Every time I think “this would be fun,” I add it, jump back in, and lose another hour. I’m having as much fun building this as playing it. Every new feature makes it harder to put down.
