You've heard of Batman no doubt, but if you don't read comics, it's conceivable that you might be unfamiliar with Arkham Asylum. The iconic psychiatric hospital is essentially Gotham City's Alcatraz, and it has housed just about every villain Batman has ever tangled with at one time or another. Now, thanks to Eidos and developer Rocksteady, Arkham is also the setting for a great third-person action game in which the lunatics take over the asylum and only you can stop them. As Batman, you not only get to go toe-to-toe with thugs in fast-paced punch-ups, but you also employ satisfying stealth tactics, play with great gadgets, solve some remarkable riddles, and do a decent amount of detective work. In short, you get to do all of the things that you want to when you don a Batman costume in a game, provided you weren't hoping to get behind the wheel of the batmobile.
