Man nothing against the US but this time period would be horrible to play as them. They weren't a super power and could have easily have been destroyed if anyone wanted to destroy them. England have many times more soldiers then the US had people so if they wanted to(propably wasn't enough money making in it for England) they could have anahaleted them. They weren't always a super power. Also they would start half way through the game. IMO an indian or denmark or portugal would be much more interesting and more realistic.
