Joshi, by your logic, nobody would play an Indiana Jones adventure game because, after all, the Indiana Jones films are filled with action and there's not a lot of opportunity for action in an adventure game.
Ideally, a good Batman story would naturally involve a lot of detective work and snooping around. At least as much detective stuff as action. Remember, Batman is as much a detective as a crimefighter. He's as smart as he is tough. Probably even smarter. Batman's beaten Superman pretty much every time they've fought. Not because of physical prowess, but because Batman is much smarter than Superman. Batman has escaped every deathtrap he's been trapped in. It's because of these things that I think you could make a great adventure game based on Batman.
