Vibe Coding NYC Adversarial Policy Simulator with Claude Opus 5
ZeroStateReflex · x · 2026-08-02
A developer shared their 'vibe coding' project built with Claude Opus 5: an adversarial policy simulator for New York City called Upzoned.
Unlike classic city-builders like SimCity where the player has god-like power, this game introduces NPCs acting as rivals (such as NIMBYs and special interests). Players must fight through the ULURP process against these opponents to upzone the city.
