Summary: Well if you played Arkahm Asylum is more of the same, not more improvement in graphics or sound, but you can play as Catwoman and Robin in his own episodes and this is awesome! The area of the game is much larger! So if you liked Arkham Asylum and liked, them you will enjoy this game! Great Deal.
Summary: Game of the year edition is totally worth the buy. Every batman suit is available from the very beginning, Harley quinns revenge, catwoman pack, robin bundle pack, nightwing bundle pack, arkham city skins pack, challenge map pack.
