Fun and good story brought down by bugs.
Then there's the multiplayer aspect. Multiplayer is basically the same as brotherhood except now there's a mode where you don't get a compass pointing towards your target but it just makes his/her icon brighter to indicate you're either closer to him/her or if the target is in your sight. Then there are also little whispers that get louder when someone is about to assassinate you. The multiplayer community is very weak, seeing only the same 50 people i play with every time i try to play multiplayer.
Overall, in my opinion i felt like this game had potential to be incredible, but not necessarily as revolutionary as Assassin's Creed II. Story is well done, but the bugs in game play had brought me down so terribly i decided to give up. With the Ubisoft team on the works on Assassin's Creed III, i can only hope that this time they won't decide to update the game whereas it was flawless and had virtually no bugs to a game that somehow became shat on by bugs.
