I really enjoyed Assassin's Creed II and this one improves upon everything, and I mean everything, in that game. If you liked that game, you will love this game. Notable improvements/additions are the Leonardo DaVinci weapon missions, the Assassin training system, the Borgia towers, and the improvements/renovation system. My personal favorite change that makes a huge difference is the kill chaining system whereby you can effortlessly flow from enemy to enemy while taking them down in style. It reminds me a lot of the recent Batman games and it works perfectly. Unlike Assassin's Creed II, the story to this game pulls you in right away rather than a bunch of filler missions at the beginning. I can't say enough good things about this - Ubisoft has a great thing going with this series. While I heard that Assassin's Creed Revelations was a step back, I'm still very excited to check out Assassin's Creed III.
