Gamasutra - Rocksteady's Sefton Hill Unmasks Batman: Arkham Asylum

Never in Batman should you watch a scene and find what you’re doing has not changed, or the importance of your actions has not changed in any way. You learn something new that makes you think about the story in a different way or want to do something in a different way. It’s quite easy to write a lot of scenes on paper, but they’re not affecting the play experience. We really wanted the cutscenes to do that when you played the game.
