This is actually insane. A vibe coder just built a complete Minecraft clone in a Red Dead Redemption-style town with Claude Fable 5.1, ALL IN 1 SHOT! The AI generated bars, a train station, NPCs, buildings and a playable open world from a single prompt, showcasing just how far one-shot game development has come. ChrisGPT is among several builders stress-testing Fable 5.1 this way, claiming the model is definitively 10–20% better for game development.(Coin Bureau)
