Dungeon Master is a game brought out for the Amiga and Atari ST in the late 1980s. It was a revolutionary game for it's time - possible a very early pre-cursor to Doom.
Dungeon Master Java is a remake of the classic game. It's a reasonably faithful clone, and I'm trying to provide additional resources for it on this site:
If you have an original dungeon, send me the URL and I'll put you in my DMJava links list. If you have nowhere to host your original dungeon, either pick up a free site from tripod or freeservers or send me it and I'll add it to this site.
