On the more less-D&D-but-more-maze-with-potions-and-monsters side of things, and at the risk of blowing my own trumpet, why not try Ravenskull, which I programmed for Superior Interactive? (www.superiorinteractive.co.uk)
Anyway, did you write the original Ravenskull, or convert it to PC? I vaguely recall owning this for my trusty old Acorn Electron when I were a lad, but there were a number of these types of games it could have been another one... In any case, Kudos!
