Assassin's Creed is one of the few game titles that I have really bought into. In Brotherhood, the graphics are superb, the engine is near flawless - the combat is ever-improving.
The only problem that I have with Brotherhood, if you had played AC2, this would've felt like an expansion pack rather than a whole new game. Yes we've gained new weapons, new location and new quests to complete. But the game was generally a refined AC2 version which was superb already.
The story-line whilst would've been excellent for any other game, did not quite live up to AC2's story line in my opinion.
It's well worth buying, but if you played AC2, you might be left a little bit disappointed.
+ New Weapons & Shop Quests
+ A lot of side-quests that don't affect the storyline
+ Easier travel between locations
+ Improved multiplayer
- Side quests mention Borgias, after they are long gone
- The storyline shorter and less engaging than AC2
