No way. Assassins Creed 2 is a much better game than Assassins Creed in every way. The main character, Ezio is much better than Altair. More variety of things to do in the missions. Lots of hidden items to be found in Assassins Creed 2. Assassins Creed 2 setting in Italy was a much better setting than the Middle East.
Assassins Creed 2 was definitely one of the best games of the year alongside Uncharted 2 and Batman: Arkham Asylum.
