The greatest superhero game ever made, with only one flaw.
Now to the story. The acting is superb, and Mark Hamil plays the part of the Joker with aplomb. The story is intriguing, but doesn't get in the way of the actual gameplay. It pulls off a delicate balancing act with near perfection between the two extremes (games with no story whatsoever, and games like Final Fantasy that are more story than anything else). The atmosphere at Arkham Asylum is also moody and dark without straying too far into a survival-horror style game. The graphics are quite good, though bland textures occasionally appear. The only problem I had with this game.. Well I lied, I have two problems, but one is just nitpicking. The nitpicking is that not getting to fight certain villians feels lame, but the boss fights are good as it is. The second is that you never get to drive the Batmobile or use any of Batman's awesome bat-themed vehicles. But I guess the developers had to save something for the next game.
The verdict: A game that is hovering between 9.5 and a 10.
