Originally, Dungeon Master was started with the name Crystal Dragon. Doug Bell and Andy Jaros began development in their development studio PVC Dragon, before they joined in 1983 FTL Games.[1] It was finished there and published in 1987 for the Atari ST first. An almost identical Amiga version was released the following year that was the first computer game to use 3D sound effects. The game was also ported to PC, Apple IIGS, TurboGrafx-CD, SNES, Sharp X68000, PC-9801 and FM Towns
