Arkham Asylum is a really good game. Outside of some sub-par boss battles (like the Final Boss) the game is an overwhelmingly good experience for Batman fans. Combat is simple and the real fun and challenge of it is just getting off all the special moves and keeping up your combos. Traveling the island is awesome and it really has a Zelda approach to exploration where you can go to many places but tools you unlock allow you to go to newer places so going back to old locations brings new experiences. The Killer Croc boss fight is fun and I love battling Scarecrow. The real fun is just exploring the place and unlocking all of Riddler's clues, he really ties the game together for me because he makes you use all the platforming elements and keeps you more focused on the environment than a typical game would have. I need to star Arkham City soon...
