If it's crap ... We'll tell you
I highly recommend it, amazing game. One of those titles you stop playign and just keep thinking about. You should plenty of time to enjoy this game before Skyrim.
If anything check out the first minutes of the game
I just finished it. The gameplay hasn't changed much from Arkham Asylum. Graphics pretty much the same as it's predecessor as well. The only thing that really changed is the story. From a comics perspective, I suppose it works. It's wildly out there. In a logical sense, it's ridiculously nonsensical. Than again, it's Batman; doubt people take his stories very serious.
Either way, I'd recommend it. The score for the game is great, the presentation is good, the characters motives and voice work are done well in connection to their comic counter-parts, the design work is decent but seems to be catered to 13 year olds who want everyone to have giant muscle-bound freaks(they really screwed Bane's design), with scantily clad women, and although slightly retarded, the main story of the game is passable for a fun game. So yeah, give it a shot.
That's only one facet regarding the silliness of the story. I like how every inmate(including ones with no affiliation to any gangs) are automatically triggered to fight Batman if they see him. Cause I'm sure Batman put them ALL in prison on his own, right? Would've been nice if there were some inmates who were on the fence regarding the situation.
Not to mention, the most glaring problem is Dr. Strange and how he keeps mentioning the "Protocol 10" secret plan throughout the game play. Eventually, Protocol 10 is revealed to be(***SPOILER***) a way for Strange to kill off all Arkham inmates in the city.
Here's the thing: If his initial plan was to kill off ALL the inmates and baddies, than why didn't he just keep them locked up in Arkham Asylum(a smaller, easier to maintain location) and finish them off there? What was the point of GIVING them a city to roam in? The only reason I think it was done, was for gaming purposes, so the gamer can have a more expansive environment to play in, ie Sandbox game play. Otherwise, the city element of the story is a horrible idea in the logical sense.
There are other problems, but essentially, it's just a game, and it's story elements cater to the gamer's interactive elements. The execution of silly ideas, though, is still enjoyable. It's a good game.
