He might not be the main villain in The Dark Knight Rises, but the Riddler has a much bigger role in Batman: Arkham City. I thought the riddle/trophy hunting meta-game in Arkham Asylum was one of the best parts of that game, but this time Riddler looks like one of the main bosses. We've already seen that you can interrogate his thugs to get trophy locations, but it also seems that you can decode his anagrams with the cryptographic sequencer. October can't come soon enough.
