So far we've gotten: LA, New York, Miami, and kinda Las Vegas and San Francisco.
But I struggle to think of any others.
Chicago is a cool city, don't get me wrong, but aesthetically it's kinda boring for a video game setting. I think Boston is too old to set a game where driving in a major mechanic, who wants to drive through those streets? Not Bostonians based on the ones I've met. And DC, nah fuck that!
Only ones I could maybe think of are New Orleans and Philadelphia. Honestly GTA Pittsburgh would be a risky but potentially interesting choice.
Idk, anyone want to play GTA Cincinnati?
I never got around to it, I've had a busy few years, is it good?
No idea, also never got around to it. Maybe if it goes on super sale I'll try it some day.
