Very fun mechanics and combat, Even non batman fans should enjoy Arkham City.
I have to say that the game was very good, my favorite thing by far was the combat system and the game controls in general.
Story 7.0:
The story was definitely not the best, there were some interesting aspects but you can tell that more effort was put into other areas of the game.
Gameplay 9.5:
The gameplay is by far the best part of the game and pretty much makes the game, roaming around and gliding in your batman suit around Arkham City is just a blast. The combat is also one of the best i have seen in any game to date.
Sound 9.0:
The voice acting is superb, especially for joker and harley, I also love the conversations from some of the citizens of Arkham City while you are roaming around, some of them are especially funny since they taunt on how they can beat Batman/Catwoman if they ever meet them (then a few seconds later getting beat down by Batman/Catwoman).
Replay Value 7.0:
Not much in terms of replay value, since you don't have any choices the story will not change if you play it again.
Concluesion:
It was a great game, i thought the story was a bit lackluster and maybe a bit short considering the style of the game, i did however enjoy every minute of the gameplay and combat which i thought were outstanding.
