As a fan of the Hush story arc, I'd love to see that as the main plot for the next game. Lots of villians, supporting cast, and story twists, but it might be too "inside baseball" for people that don't keep up with Batman that much. An open world Gotham is the next logical step, but hopefully the gameplay gets switched up. And no more Riddler trophies!
@TEHMAXXORZ: The offer started this past weekend. Check your account, because I think those who preordered before the deal went live also got the credit. Also, CAG may have some amplifying info for you.
