AC was very monotonous, because the emissions have repeated in every city, so comes with AC 2 will not be bored.
There are many new features, as well as weapons, freely selectable missions, forging, Doctor, ...
The game has inspired me from the very first minute, also because it is much more dynamic than its predecessor. In addition, the structure of the game means that you can identify very well with the main character of the game and the story is denser than at AC.
For me one of the best games on the Xbox 360 console.
BTW: You have to no longer torment so if you want to have all the success)
