It's a given that games developed in America will make America the center of every future Earth. Japanese culture does the same for itself (see Code Geass or many other animes where the future of Earth is determined on the soil of Japan) except when dealing primarily with a Western audience (which, by the way, is quite a rare situation for them).
However, I must say my patience is wearing thin concerning American protagonists as well. I'd like to see a serious, next-gen game set in Australia, minus all the more stupid clichés. We're like America, only we have a slightly different accent, and we're England, except without much arrogance and with some extra toughness inset in the culture. We don't actually often say "mate", except to stupid tourists who expect it, most of us don't learn boy scout-like survival tactics, and again very few of us wear cowboy hats like Dundee - GET IT RIGHT. Our country is like 60% desert, though we mostly ignore those areas.
Sounds like the perfect middle ground for a fictional WWVIII to me, except there is one thing Australia realistically lacks - power. However, we could gain it in such a large timespan. Remember that board game Risk? Get Australia and you win. There's a reason for that. No one pays attention to us and we very, very slowly build up, while America and the other big countries waste their tough people on pointless wars. We contribute, but we're hardly losing the majority of our defence force over it.
