i think the only reason batman works in a game is because he is just a normal person. unlike every other super hero who has powers batman relies on his own skill and intelligence and the fact he is only human and can die (he got killed off in the comics) it translates into a game well.

i would find it hard to get into a superman game due to who he is he is the best at everything and virtually immortal so where is the challenge.
