Motelsoft is a German company which sells many shareware games.
Over the years they released several games inspired by Dungeon Master, many of which can now be freely downloaded from their web site.
On Atari ST:
- Arcan
- Darkstone Ritual
- Projekt Terra
- Walls of Illusions: This clone was released as a shareware in 1993. You can download this game at the Wall of Illusions page at Atari Legend. This version has some nice features like an automap but the gameplay is not as good as in Dungeon Master.
On PC:
- Escape from Ragor
- Megrims Rache
- Dark side of sun I, II and III
