Warning: the following is a discussion on the ending to Batman: Arkham Asylum. Very explicit details about the ending will follow. You’ve been warning
Batman: Arkham City has a lot in common with its predecessor. Arkham City simply improves on Arkham Asylum by increasing its scope and ambition. Instead of a normal prison, you have city-sized, super prison. Instead of one central villain, you have several whose factions are at war against each other. And instead of a stupid and unsatisfactory ending, you have a passable but mediocre conclusion.
