I don't get how people don't see it. How many games set in modern cities (or near-future) don't use american cities as locations? Or fictional cities that are american in everything but name?
Well, here's a list of the games I'm currently playing:
TES: Skyrim (fictional universe)
Mass Effect trilogy (fictional universe)
Borderlands 2 (fictional universe)
Deponia (fictional universe)
SimCity2013 (generic everywhere cities, with specific DLC for European tilesets)
Of the games that fit your specific criteria I'm currently playing:
Saints Row 3 (Fictional US city)
Sleeping Dogs (Hong Kong)
Just Cause 2 (Fictional country in Malay archipeligo)
Keep in mind the question isn't specific to certain genre's. It simply asks "Are you tired of games being set in US?" For me the answer is no, since most of the games I play are set in entirely fictitious universes and even of the ones that meet your criteria, most I currently play are set in Asia.
