This seems like as good of a place as any to start making a list of what is needed to accomplish the "Historical Triplet" Achievements in the game. So far, I've been able to win the game with two different ones:

American Dream - You need to have Democracy as the government, finish the Fast Food Chains Wonder of the World, and have a Professional Sports (Age 3 Arena) built.

20th Century Stigmas - Start two wars (I don't know if you need to *win* them) as well as seed the Cold War from the event deck.

Has anyone else got any of the other ones? If so, how about sharing what you ened to get them...
