If you like Diablo 2 you would really enjoy Titan Quest Gold edition on Steam. It's basically a blatant rip-off of Diablo but with better graphics, based on Greek mythology, and better controls.

Another game I would suggest is Trine or Torchlight also found on the Steam Network.

What come to my mind..
In Fantasy genre:
Titan quest, Torchlight, Fate, Sacred 1&2, Silverfall

Sci-Fi genre:
Space Siege, Shadowgrounds and Shadowgrounds Survivor

Titan Quest $ 4.95 at D2D

The Witcher
and the upcoming The Witcher 2.

Here is a short fighting sequence

The Witcher is a good game indeed and i'm anxiously waiting for the next one. But those are nothing like Diablo 2 or Dungeon Siege 2.

I like Torchlight - it's a good diablo clone, with nice graphics and sound.
Very repeatitive, but still enjoyable. (I call it diablo 2.5   )
cost me 5$ on sale on steam, should be 10$ now. Totally worth it imo.
