He also knew that once someone could shape the currents of a city — even small eddies — they could steer consequences. He imagined rerouting a protest away from a hospital, redirecting an embassy convoy into a traffic jam, clearing a lane for an ambulance with a script that made every nearby driver play along. That kind of power was corrosive; it also tasted like leverage. Forza’s physics are too forgiving; GTA’s are cartoonish;
