Nat China, 1937 Marco Polo bridge start...
Followed by the major powers:
UK '39 --> Germany '36 --> USA '41 --> Soviet Union '41 --> Japan '44
With UK I'd go for world conquest. With Germany, I quit after conquering SU and USA. With USA, after defeating the axis. With SU, after defeating Germany and USA. With Japan, I'd pull out of China, then see how long I can survive ... ...
Except for Germany, I don't like the idea of waiting for war, while knowing I'm being being out teched by Germany. As for all of you who are saying you are going to start with minor powers......

why?! There's no action!
