Nope, it's basically a prettied up Diablo clone, best taken in small doses. I hear multiplayer can be fun, but I wouldn't know as like most multiplayer games, it's dreadful on dialup. I finished it, then traded it in. Some of the stuff I've read about DS2 has me excited, namely they've been listening to fan feedback, and have decided that contrary to what they though, we do want micromanagement. They also talked about this neato pet system, and said they've hired pro-writers so there should be an actually good story this time around.
What I'm saying isn't a knock to it, it did what they wanted it to, which was a fast paced game, with a pretty engine, they kept the player in the action. I expect the second one will do what they want as well, but I'll still read a couple of reviews as I do with all games now (I don't purchase much of anything on a whim these days), and see how it turned out.
