NoX was a Diablo-esque game for PC that came out about 12 years ago(?)
It was pretty rad, it focused on a set main character but you could make him be whatever you wanted (spells, melee combat) whatever you picked changed how the story panned out (same endings I think though, I only beat it with two of the class choices) it had multiplayer (think Dead Rising 2 with the 2 Chuck Greens) and had a competitive PVP mode. It was pretty fun, and had a decent yet silly story. I lost my CD key years ago and always wanted to replay it. If you can ever find a copy/cdkey I highly recommend it.
