Sounds epic! Imagine a skyline that morphs when the player votes on a council debate, or a whole district that rewires itself when you sneak into the archives. The key is making the changes feel earned, not just a gimmick. Maybe start with a core mechanic that tracks choices, then layer visual changes on top. I’d love to hear what your initial concept looks like—share a sketch or a quick prototype and let’s brainstorm how to make the city breathe with the player’s hand.
