Truth is, 2007's Assassin's Creed, released for the PS3 and Xbox 360, sold millions. Over eight million in fact. It lays claim to being the fastest-selling new IP ever. In short, it was a huge success for Ubisoft. All this despite it being a bitter disappointment for the vast majority of gamers. Why? Some found it repetitive. Some found the combat boring. Others slammed it because Altair couldn't swim. The inevitable sequel looks set to right those wrongs. Including the swimming.
