It's probably one of the least-explored genres out there because most developers believe that people don't want that kind of escapism that's too close to everyday life, or that it's shallowly followed where most games would fall somewhere between zombie apocalypse and urban life simulator. One I can think of that isn't mentioned is The World Ends With You for the DS, which is kinda hard to find given that it's been a while since release and those who have it aren't going to part with it that easily.
Speaking of Square Enix, I guess you could say that FF14 is one too, since the design seems more like stuff they pull out of what they see on city streets instead of completely out of their minds. :x
(Bethesda should jump on this kind of opportunity though)
