It doesn't have to be a small area like Arkham Asylum. Make it open world GTA style Metropolis. You fly around stopping random crime like an armored car or a bank robbery and then you also have the big story missions taking out super-villains along the lines of Metallo and Livewire. Throw in some reporter missions as Clark Kent and you've got yourself a game.

Maybe make it where when you're Clark asking people about a villain it gives you tips on how best to approach them. Say Parasite attacked Hobs Bay you talk to a dock worker that says he saw this big purple guy suck the life out of one of his buddies. Then it gives you the tip to keep your distance and use the environment to take him out. Something along those lines.
