Eh, I like the style of torchlight (dungeon crawler), but this one felt too repetitive and I really hate the type of graphics it uses. I was done with it after about 40 minutes of play, and I know for a fact that it doesn't have multiplayer for the 360, i forgot whether it had it or not for the PC (I don't think it did), so it'll be a solo game if you get it. Also, since it is in the style of diablo 1&2 you'll just be pointing and clicking, but the game doesn't have as many cool looking skills and powers to make it less boring like some of the other better point/click dungeon crawlers out there. So, if you don't mind silly over-sized, super bright and blocky style graphics (similar to warcraft 3) and you don't mind basically point and clicking for the entire time, you might like it.
PC didn't have Multiplayer either, but it's open sources, so it's open to the MOD community. So there are a lot of mods to be had. The XBLA version doesn't use Point and click, it's more on the vein of DeathSpank in that regard. Run around and bash stuff up. It's a great game if you're a fan of Diablo 1 and 2 imo..
The sequel coming out this year is going to have Muliplayer, and more customization, but the art style will be unchanged.
