There seem to be a proliferation of different variations of random dungeon generators out there. I've never much liked them, mainly because they never seem to be designed in any logical way. Not that cave complexes and such are designed in specific ways, but dungeons, towers, castles, etc. are usually designed with specific functionality. Just wondering about others' use of these types of programs. Do you use them? Do you not? Why or why not? If you do use them, how do you plug them into your gaming sessions?
