Well, seeing as how it's the revolutionary war, and the game is made mainly by Americans (I think?) I'd be surprised if the general tone wasn't "KILL ALL BRITS," never mind it being impartial.
Mind you, it IS assassin's Creed, and correct me if I'm wrong, but the general way an assassination works is quietly sneak up to targets, play yourself off as no-one special up until you reach them and then gank them and flee. So, ya know, there's opportunities to have the Brits talk about, I dunno, tea drinking or how they're missing their families something and make the war seem like two sides of gray (or, if you want to be slightly more pessimistic about it, two groups being dicks to an equal degree) instead of Good Americans verses Eeeevil English Redcoats who bayoneted innocent babies for the evilulz.
Of course, history has a way of painting the winners as the good guys, especially in recent wars, and especially especially if the people writing the stories about the wars are the winners themselves. So, ya know, personally, I won't take offence if we were painted as a bunch of baby murdering sons of bitches who needed to die in a pit fire, because, let's face it, at the time? You guys must of seen us that way for the most part. Hell, OP at the end proves some of you still bloody do, even in jest. x3
One tiny thing, to American game WW2 game developers in general, though - can you PLEASE give us SOME credit for the Nazis? I know you had to basically come save our ass with loads of tanks and bubble gum, but at least say we helped!
(I know you're getting better, too, but still, please.)
P.S. OP, I demand satisfaction. Acquire a rapier by any means necessary and bring it - along with yourself - to the address sent by P.M., and we shall face each other in combat to the death for saying we were the bad guys. 3:<
... Wait, what do you mean, the other guys were joking when they organised a duel? Fuck!
