Holy shit! I was just thinking about this game the other day.
Way back before you were born (1983), I used to play this amusing little PC game called Rogue. Then came its descendant Hack. Eventually Hack became NetHack which, honestly, I didn't find as much fun. I played Rogue and Hack for hours. Hack could be beaten, which is probably why it evolved into NetHack and became much harder, but I've only beaten Rogue once. I've found the Amulet of Yendor maybe five or six times, but only gotten out alive with it once.
