User blog:SLyfoX999/Which Assassin's Creed should I get?

I am wanting to try Assassin's Creed but don't know which one to get! I have never even played Assassin's Creed, but think it looks awesome! Assassin's Creed 3 is out of the picture, because it's supposed to be the resolution and I wan't to know a little about what goes on.
