Playable Mario Kart game recreation

Claude Opus 5.5 just ONE SHOT a Mario Kart game. The result is way better than Fable 5.1. The attention to detail is on another level. Opus 5.5 actually created real characters. Mario, Luigi, in the game, playable. Fable 5.1 has never done that. Insanely impressed. This model is different.
