I think it was well executed for what it was, but that ultimately it was a real world location in a post-apocalyptic/collapsed state. Not particularly novel, and being grounded in reality, it's all very same-y for lack of a better term.

Still loved the game for the time myself and my buddies got into it, but at some point, it just didn't hold our interest. The game mechanics were very well designed, though, albeit somewhat overwhelming at times.
