I've actually heard the opposite, playing the demo I agreed. The combat was slow and clunky, the attacks were boring and uninsipired and there were at launch anyways, a couple of bugs in the multiplayer. I think you should pick up torchlight if you want the best dungeon crawling experience on xbla. Epic dungeon(indie game) is awesome for a dollar too. If you need it to be multiplayer, sacred 2 is good. The new dungeon siege might be okay too, that has a demo on xbl marketplace if you want to try it. The demo has online co op too to test that.
