These lists are amazing.

Here's mine...

1. Ultima V - This was my first computer RPG, so it wins both on merit and nostalgia.
2. Might and Magic III
3. Quest for Glory I (the original version, when it was called Hero Quest)
4. Baldur's Gate 2
5. Wizardry VII
6. Daggerfall
7. Wasteland
8. Starflight 2 (especially because death = no reloading your game.)
9. The Seventh Link (I had this on a coco3 computer. Possibly before I had Ultima V... Actually, does anyone know if this game can be played today via an emualtor or in any way what so ever?)
10. The Bard's Tale III

Can only think of a top 9 (in no particular order):
disgaea (series)
the bards tale
dungeon master
ultima 4
final fantasy 9
dungeon siege 1
oblivion
demon's souls
dark souls

From my list, you can tell that I prefer old-school rpgs and some of these are REALLY old). Incidentally, these were all played on a Mac.

Xyphus
Wizardry: Proving Grounds of the Mad Overlord
Quarterstaff: The Tomb of Setmouth
Ultima II
Pool of Radiance
The Bard's Tale
Might and Magic I
Realmz
Exile: Escape From the Pit
Diablo I

Very interesting nyte. Ive been trying to hope that good old games will eventually put both pool of radiance games up on gog. Im guessing that you played the original when your computer was the same version back then?
