I prefer WW2 over any other type of war. I don't care if there's over 9000 of them, but I hate this modern warfare crap. Counter-Strike and Battlefield 2 are my only exceptions to the modern warfare thing.
WW2 was the last justifiable war America fought in so it's understand why they would want to to pick it...I mean, nothing is as easy to sugarcoat as that war.
