I think we can all agree one of the main draws of the BioShock series are its exotic locations. It's almost unthinkable that future BioShocks won't try to wow us with new exotic locales like the underwater Rapture or the floating Columbia. My question is: what could those settings be? The rest of the world is still sort of like RL, so it can't take place anywhere and after going underwater and up in the sky, the obvious types of exotic high-tech city are somewhat drying up. The only location I can come up with at the moment are space/the Moon. Anyone got any other ideas?
