I will save everyone some trouble who is about to play AC the first time. After you get through the first, oh, three or so missions, there's not a whole heck of a lot of need to keep playing, unless you just loved the hell out of what you just did, because it's virtually the same exact thing for the rest of the missions. The missions get a little more challenging and the Templar guards start becoming more the norm (by the last mission, they've virtually replaced the standard guards), but what you do and how you do it and what happens in the story is all largely the same. I give them a pass because they were still figuring out two different brand new consoles at time of development.
