Yeah I admit I never looked in to it deep enough its just that it never really caught my attention that much, maybe because I though of it to similar to MVC games as for what I meant by "if you learn how to play with one character you can pretty much use all of them" is that all characters pretty much follow the same pattern where you pretty much have to figure out how to juggle your oppomnet in the air an beat the crap out of him by using your character combos
Edit: my favorite character was Chip but the pros where I live kept telling me that he sucked
