Batman: Arkham Asylum.
Three words and you have brought up what I consider the greatest videogame adaptation of an existing comic-book in history. Everyeone I know that played it fell it love with it. From the voice cast of the 90's Animated Series returning to most of their original roles, to the amazing art design, the smooth fighting system that really made you feel like Batman, and the well designed ability to sneak around like a Dark Knight and drop entire groups without a sound.
What do you do after making something that highly regarded by both the comic-book and videogame communities? Three choices really. 1: Let it be a one off we love and remember and move on. 2: Try and repeat the same thing and hope it flys. 3: Go all out making it bigger, smoother, and deeper than the original.
Thank you Rocksteady for choosing door number 3.
