Yeah, if I had one knock on the game, it would be the lack of overall difficulty (in anything other than getting the seals, which still aren't THAT hard), but if they make improvements like they did from AC1 to AC2, I have faith it will be an even better game. The graphics and the storytelling in this game are absolutely phenomenal if you're into history from the time period, and I think that the few gameplay issues will be addressed going forward (or at least I sure hope they do)
BTW, for what it's worth I've heard that all of the DLC (downloadable content) levels are/are going to be decent fillins to the memory gaps when the story jumps from Sequence 11 to Sequence 14, but there are no really new gameplay elements added and it sounds like it's debatable if they're worth the extra $5 apiece...
Anyone played Battle for Forli expansion level yet?
