G'day,
I found Legacy and Undercroft (
www.rakeinthegrass.com) to be good fun and well done.
Re Dungeon Master: I had it installed on my Ipaq 3970 and it worked very well except that I couldn't see the keys. In DM keys were sometimes left by themselves in passages. I couldn't see them on the small screen so you would probably need a walkthru to identify where to search for them. They were hard enough to see on a full size monitor. Otherwise good fun - just as it was on my Amiga.
Cheers
Bern
