This game goes beyond the first....more to do, side missions and build up all surpass its sibling and ensures your always hunting for something. Whether its altairs armour or glyphs.
My only gripe is most missions are pretty impossible to do full on stealth...you`ll know what i mean when you have to assassinate a guy on a boat during mardi gras. its just not possible and thats sort of the point....to be able to slip in, kill someone and slip out. rather than run in, smash up a few guards, kill the target, smash up a few more guards then run off and hide lol.
Thats just me being picky as i never stopped enjoying this game. might help to play the first one first tho :o)
