Well, we have done a ton of Snap shots and what not. Well, lets do some very historical "what ifs?" I'm probably going to get alot of ack about it, but WAIT. Lets do something obvious that coulda had a big turn out for the war. LETS say that during Pearl Harbor, the Americans HAD been waiting. They HAD their planes ready and in the air waiting for the Japanese when they attacked. Lets say that when the Japanese first attacked the Phillipines, the Americans were waiting. What if the Japanese had ended up finding the American Carriers first?
I do not know too much about very Air battles, or significant battles involving air, but it could probably restart a whole knew type of Specail Event that we probably could not have done, or would have been very boring other wise.
I hope I dont get too much ack here about this. But I'm just opening up more possibilities for what could have been and how it could have affected the battles.
