People who are seriously into fighting games hate using normal controllers for some reason. They need one designed just for them. And man is this Marvel Edition Versus Fighting Pad designed for them.
I mean, just look at the thing! The entire front is covered in a very, very busy scene full of Marvel superheroes. But as for the controller itself, it's got the shoulder buttons moved to the front and a single, highly responsive directional pad replacing the normal thumbstick. If you're seriously into fighting games, and Marvel vs. Capcom 3 in particular, this might be right up your alley.
