I would have bought this game if it was historically accurate. Yeah I get to fight with the Founding Fathers except most of them were Free Masons who are associated with the TEMPLARS! WTF?! So I'm fighting for the Templars now

As for the slaughter that began the story, Colonists and their militia were responsible for more deaths of native americans than the British. That's why native tribes like the MOHAWKS sided with the British.
Wouldn't it be cool if you were an Assassin fighting for the British against the rebel colonist who were secretly controlled by the Templars. Benjamin Franklin could be your nemesis. Of course Ubisoft loves money more than history so we get AC the American (Lame) Revolution version.
