Besides a few glitches, it's one of the best AC to date.  The graphics, story, and hunting missions are brilliantly executed.  It's a must have if you're an AC fan, or want to play a great game.  I must forewarn achievement/trophy hunters (especially if you like to complete every achievement/trophy); 100% sychronization is horrible and ridiculous, which is a real headache and will have you saying words that you wouldn't repeat in front of your parents.  Besides that, it's a blast to play.
