Why Ass Creed 3 will not suck:
1. It is not The United States, it's 13 British Colonies. Meaning it is so far removed from knocking back a Budweiser and watching NASCAR (or knocking back a Pabst and listening to NPR) that going AW SHIT AMERICA is a bit pre-emptive.
2. The main dude is definitely not a colonist. He's an american indian, so for those not in the know, that makes him both loyal to neither side (No AMERICA FUCK YEAH here) and capable of fucking shit up on both sides (it was not exactly a happy prosperous time to be alive, people).
3. Guerrilla tactics and melee weapons are perfect STILL - think The Patriot, except that instead of Mel Gibson chopping people up and hiding in trees, it's a full group of Assassins who then chop EVERYONE up.
4. BEST OF ALL - this takes place, chronologically, leading up to the French Revolution. As you know, the French were pissed at the King for (essentially) pissing all their money away, and one of those golden showers landed on the colonists because King Louis the 16th still hated Britain and wanted them to suffer a big bunch. I would be happy to see the game immediately after AC3 go straight to a France on the cusp of rupturing like nobody's business.
