it's a pleasure to see so many people enjoying Dungeon Master.
I played my first Version on an Atari ST in 1988/89 and I must say, that this is one of my favorite all time classic games! I played it on these Platforms
ST (DM, CSB) Amiga (DM - there is said that Version 3.60 has some improved graphics and new sound but I didn't notice any difference), CSB) PC (DM, DM2) X68000 - I didn't get it to work...

I get most fun playing the amiga version, because it is easier to start WinUAE than going to DOS-Mode and has better sound.
In 1989 I started a team of 4 characters (Hulk, Hissssa, Elija, Chani)on the ST and trained them to MON Master Wizard, just to see if there is something after Archmaster (using some items which improve your stats). This took me more than half a year running from the screamer room (worm level), killing some worms, killing those 4 green beasts below (in the floor down to the riddle room, usually they regenerated after a visit to the worms upstairs), killing the skeletons and those yellow beholder things, ..., killing some rats in the rat level, and then going up to the screamer room and starting all over again. Sometimes I went up to those blue guys and wiped them out, too

I never got down to lord chaos in this time , because I didn't know how to kill him. I tried it with usual weapons forsome hours but it didn't work (it was a good training, though!). A year later I read a walkthrough in a game magazine and finished the job. I was somewhat disapointed - that's all? I trained my party to the limit and chaos was beaten in seconds!!!
Good luck that I was in school these days and had much time playing DM...

Once I've completed the game with one charcter (Chani). This is somewhat more challenging.
Happy fighting!
