Just how far back into ancient history are we supposed to go with this topic??
Actually, this is a tough question. I've played so many and my tastes have changed over time.
These are not listed in any particular order and certainly won't reflect any 1-10 rating.
Wiz 1, 2 & 3
Wizards Crown
Wasteland
W&W
Might & Magic - the early games
Below the Root
Bard's Tale - early ones
Diablo I - this was a great game for "relaxing" upon replay
Arena
Gads, I can't even remember any more! lol!!
