I'm currently playing the new Batman: Arkham Asylum
I must admit, the game does true justice to the comic series and does not play up to the blockbuster movies. The characters are so immersive and gameplay is interesting yet simple. The Joker actually reminds me of Jack Nickelson, who I still believe was the best, better than Heath Ledger. You also find the extra things quite interesting, the riddles, and Bio's are really interesting, even if you are not a fan of the series.
Fun to play, especially on the PS3
