Rocksteady have proven that they're a company that really care. They actually 'get' Batman, they've looked at the character from every conceivable angle and strived to make this everything anybody could possibly want from a Batman game. It's an adult presentation of an adult character, and not once does it fail to make the player feel anything other than the Dark Knight himself.
At one point last year Ian Livingstone, head of Eidos, made the bold statement that Arkham Asylum was the closest thing to a perfect game they've ever made. After multiple play-throughs and constant replaying of challenge rooms (that encompass freeflow and silent predator challenges outside of the main game) DarkZero can honestly say that while it isn't the perfect game, it's the closest you'll ever get to being Batman.
