If the inclusion of Green Arrow would cause a geek-high across the comic book community, then a visit from The Man Of Steel would no doubt trigger nerd meltdown. Not only that, but it would have some incredibly exciting implications about what Rocksteady's next gaming IP could be after they bow out of the Arkham world. It's really hard to write a good Superman film and it's even harder to make a great Superman game because the big guy's so damn overpowered. But hey, up until Arkham Asylum, Batman's pixelated adventures didn't have much going for them either. Rocksteady made the kind of Batman game that his fans both deserved and needed, doing the same for Supes would be a much bigger challenge but one we'd love to see them have a crack at. As for Big Blue in Arkham Knight, we actually wouldn't want to play as him and we wouldn't want him to feature to prominently - like we say he's far too powerful to just be slung into the Arkham world without ruining the balance. The best way to have Superman make an appearance would be in the very last scene as the ultimate tease. Save the super strength and the laser eyes for some alien threat in Rocksteady's Justice League. Which other heroic characters do you think should appear in Rocksteady's next-gen Arkham sequel?
