One prompt, a full Mario Kart game: Claude Opus 5.5 builds 8 cars, 4 maps and PvP in one shot

Developer @sseele used a single prompt plus a few fixes to have Claude Opus 5.5 generate a complete Mario Kart-style game for free on @spawn: 8 cars, 46 upgrades, 4 maps, 5 difficulty levels, and both PvP and PvE modes.
By comparison, Fable 5.1 produced just one map with no car select, no PvP, no difficulty levels, and no upgrades. Quoting the thread, @bridgemindai notes Opus 5.5 even created playable Mario and Luigi characters — a level of detail Fable 5.1 never achieved, concluding 'this model is different.'
