As you can see, DM grabbed us pretty hard when we all encountered it, and we've kept coming back to it all these years later even when better graphically or more complex games have come along. Part of it will be it was the firts game we saw like that. But really it did many things so well - the large screen and off to the side interface that games like EOTB ignored, the mysterious objects and charatcers that even now we have to fight with source code to explicitly figure out what was happening with them. As you say, there was something about that big screen where you could just pick something up and throw it - and get immersed, of course!
To one of your questions, if you reincarnate your characters instead of ressurecting them, they start off without their levels, but you can rename them. For DM it is the bett5er option as you can levle up fast and get more stats. For CSB, the rules are different (you also stats too) and..well, and as you know, there are evil worms waiting. Just because they aren't purple doens't make them any less evil!
If you do have any tales of anything connected to FTL, then Gambit and Christophe love to hear that sort of thing! Ok, we all do

Sadly, some advanced fan clones have started to update the DM engine, but none have come close yet. Happily, the fan made clones that are like the DM engine but expanded are going strong with either development still going, or simply very functional and with lots of good custom dungeons to explore.
Anyway, sleep well and hope you enjoy looking around the forums!
