I don't really care for superhero drek most of the time. I did enjoy the Green Hornet movie with Seth Rogan (whom I also don't really care for most of the time), so I'd vote for that. Since the Green Hornet and Batman both share central heroes who aren't really "super" in the traditional sense, I think it could work.
Daredevil! I'm so sad that we haven't gotten a good Daredevil game...
I'm glad I got to the end of this topic before posting. Daredevil would be phenomenal with something like the Arkham games. TMNT would be up there as well.
Another idea would be for something completely different. Have the main character be a villain. A game based around the comic book Green Goblin would be pretty cool. --- PSN - Srikar || WKC2 - Jinto My car: http://img708.imageshack.us/img708/8583/86coupe.jpg
