I think Telltale should stick to comic book properties, the engine they use really makes it look like a comic book come to life. I wouldn't mind seeing them take on Batman, plenty of the Bat's best stories are less about his punching someone out, and more about the relationship between him and his enemies and the rest of the bat family. It might also be a better showcase for his detective skills, rather than the emphasis on his combat abilities other games do.
