Demo on steam, its only $20 to buy...
Its like they sat down one day and said: "You know what was a good game? Diablo. We should make a game like that, but make it more like... Diablo. That was a good game."
Seriously though, the similarities are so much that it is crazy. Just play it and you'll see. It is way improved though, although there's no multiplayer.
I think they're going to build this into a MMO sometime in the next year or so, which would be interesting. In the meantime though, VERY solid.
