I know this thread is a bit outdated but here are my two cents
My favorite RPGs are mainly played back in the days on my AMIGA 500 (1 MB Ram, 2nd Floppy):
1. Dungeon Master 1 (and after that "Chaos strikes back" expansion disk)
2. Xenomorph (Awesome Sci-Fi dungeon crawler game a la Dungeon Master !)
3. Eye of the Beholder 1+2
4. Black Crypt (never played to the end - sorry)
5. Amberstar, Ambermoon (never played to the end - sorry)
Later on the PC
Wizardy 7, Eye of the Beholder 3, Lands of Lore 1&2, Titan Quest
Playstation 2
Baldurs Gate 1&2
Sorry but the Diablo Stuff is not the way I like RPGs to be played (only my point of view)!
My favorites are definitly the "Dungeon Crawlers" with grid based movement, solving a lot of puzzles and a very unbeatable atmospehre. Dungeon Master and especially Xenomorph are my all time favorites
