One prompt to Opus 5.5 produces a playable Civilization-style HTML game

BenBlaiszik ran an experiment: a single prompt to Opus 5.5 produced a Civilization-style HTML game — and it's actually playable.

The result includes a legit tech tree, units with different capabilities, AI players, diplomacy, a story, and things to discover on the map. The author notes there's room to grow, but as a single-shot generation it's impressive; demo at the link.
