I don't think you can play "Dragons of Despair" with DC, unless you converted it first.
I had a very weird experience last night. I was thinking about FRUA, so decided to look through the directories of games I had currently available (not counting my zipped archives) and saw a folder name that didn't look familiar from downloading at Rosedragon. I started playing it and was having a good time until a band of kobolds wiped out my first level party (they would have been fine if two of the fighters hadn't been mauled by a cave bear). I wanted to see who made it so I could find more of their stuff if the rest of the design was as fun to play. I opened up the readme and saw that the mod was started in 2001, which is a few years ago but did have some good art. Anyways, I looked at the mod author's name and it was... (any guesses here?)
