I would be very interested (or maybe not) to know if the console version was dumbed down difficulty wise. Not, because if it's the same game and people are destroying it with a controller...well then I really do suck.
I have absolutely no idea how you could play this game on a controller, not referring just to the platforming. How the hell do you fight a Marauder on a controller, never mind one that's surrounded by an army of demons. As others said, tons of systems and chaos.
