You will be in love with this game. Just for how long?
With new everything.
Its a new time and that means we need a new assassin. And who is that? Ezio Auditori Difrenze. The most deadliest assassin of all time. With new skills, weapons, moves and more. If you played the first Assassin's Creed it will start were it left of. Desmind will end up escaping right when you start playing. When Desmind leaves Desmind learns that he is a assassin and you must learn the ways of the assassin by going through the memories of Ezio Auditori. Everything Ezio learns Desminds learns.
Graphics are amazing. If you have played Grand theft auto 4 you might feel right at home because graphics are almost as good as GTA's. Shadows are perfect. Even though Ezio has a little more detail than other characters its not really a big problem. When you cut a person or stick a ax in a guy's eye or stick a spear down a guy's spine a great amount of blood comes out making very realistic.
In Assassin's Creed 2 you earn money from missions, side missions,or killing a thief or messenger then looting there bodies. You use this money to buy knew weapons, dye your cloths, higher people to distract guards, buy health, a lot of things.
So whats there to do after you beat the game (8 to 10 hours). Well there is really nothing you can do. If you did not get Altiar's armor that will give you another 1 or 2 hours. You can do side missions that suck. They have all the same mission types and you get money that you really don't need, unless you don't have a weapon or you want to dye your cloths.
Assassin's Creed 2 is a great game with great graphics, action and more. There is not much to do when you beat the game but hey don't get me wrong, you might find somethings fun when you beat the game.
