Via a post in Kotaku, it seems that Mr. Nygma will not only return to plague Batman with puzzles and riddles which he must solve, but he'll also be manipulating the Dark Knight in a manner similar to the Scarecrow, who by inducing Bats with his fear-toxin transported the hero to "nightmare worlds" that gave him more than just a simple trap to overcome. If the reports about the demo prove to be true, then the Riddler may just provide a greater challenge to Batman that's in the level of Dr. Jonathan Crane's alter ego. Given how interesting and irritating Mr. Nygma and his puzzles were in Batman: Arkham Asylum, I'll brace myself for the worst The Riddler has to offer in Arkham City. We'll just have to wait and see how his role gets expanded once the game comes out this October! For more info and additional reading on this, visit the source post at Kotaku!
