I would find China interesting, see the fallout (heh) of the Great War from the other side, but I think I agree with others here that stated that Fallout will always be in the US. I would like to see the European commonwealth to see what happened there, but is it really a Fallout game then, or just another post-nuclear wasteland?. I like the idea of Berlin, London, Prague (big and flat city, lots of twisty little streets, great metro system) maybe Moscow (but that would feel too much like Metro 2033). As an aside, when I first saw Metro I though, oh wow, a whole game clawing through the dark metros that I began to hate. What I WANT though... GIANT open world. I want to be able to spend a year worth of ingame time and walk from the Capital Wasteland to the NCR. Be able to pass through Chicago, St Louis, VAST open wastelands of Nebraska and Oklahoma, NYC, Detroit, through New Vegas... you get the idea. Highwaymen, bits and remenents of other BOS groups, muties galore. Think the swampfolk from Point Lookout all the way through the Appalachians... I know this is really not feasible, but...
