I'm a big fan of Dungeon Master. My husband and I bought the first one when we moved together,and we spend many fun hours playing and exploring. I know the game so well that my son used me as a walk through when he first played it. There is only one thing I can't remember, the location of the second vorpal blade.
Now I'm playing Custom Dungeons and Black Gate was the first one I went through. 10 levels and easy to run through in a couple of hours. Now I'm moving on to the Dark Abyss.
