Batman: Arkham City (PS3). Bought this for myself today at GameStop, as a birthday present. I'm enjoying it just as much, if not more than I did Asylum. Both are easily the two best Batman titles I've ever played in my lifetime.
I'm still waiting to get Arkham City. I'm going to get it for PS3 on birthday (which is in December) hopefully along with Max Payne 3. Could have gotten Arkham City last year but chose Uncharted 3 instead.
