Now that Batman: Arkham Asylum has been released, it's thrown into disarray those perennial lists of the best superhero games. But it doesn't stop there.
It also messes up lists of the best stealth games. It messes up lists of the best games in long-running franchises. It shatters any list of the best games based on DC characters. At least it would if any such list existed. It even messes up any list of games set in awesome worlds.
Although it's (mostly) confined to a single island, the developers have done an amazing job breathing life into that place, fleshing it out, making it feel like its own world. You won't soon forget Arkham Asylum.
