Well, according to Game Informer, the world of Infinite will be about a harshly nationalistic floating American city that is intended to show world dominance and the people hate immigrants.
I'm glad they avoided any overtly political statements...
Honestly, this disappoints me greatly. Not because I'm American, but because this type of thing has been done to death, and the original game was so artful in its philosophical storytelling. This just seems cheap and uninspired.
