Batman: Arkham Asylum exposes players to a unique, dark and atmospheric adventure that takes them to the depths of Arkham Asylum - Gotham's psychiatric hospital for the criminally insane...
Very good game. I only just got this last week, along with Arkham City.
Plays well, in combat and overall, along with a good story.
Played it with a controller rather than keyboard and mouse, which was very fluid.
Game is not particularly difficult on normal, yet to play on hard though.
Possibly the greatest super hero game of all time.
The only real major error of the game is the lackluster ending boss fight, and the fact that two voice actors voice practically everyone who isn't a main character. One of them is practically everywhere else as well (Bulletstorm, Mass Effect -- you name it, he's in it. He's more frequent than the guy who plays Nathan Drake).
Also, Dr. Young could have had a far greater and longer role than she was given.
