I would also have to recomend Fallout and Fallout 2, both wonderful games set in a post-apocalyptic future. Not exactly D&D, but still good games.
Eye of the Beholder 1 & 2 were very fun games and I hated 2nd Edition AD&D, but I still loved alot of those older games. I enjoyed most of the old SSI AD&D games. Granted some of those are really old and look really crappy today.
If you are looking for some adictive, mindless, hack and slash then Diablo or Diablo 2 are just up your alley.
If you are willing to really go old school I would recomend hunting down the Bard's Tale series. All 3 were very excellent games, although they are totally ancient.
Any of the Ultima series from 4 on are good. Story wise that is. Most of them graphics wise are obviously... well bad looking compared to modern games.
Off the top of my head thats the best I can come up with. Hope you find this helpful.
