Pen and Paper random dungeon generator

[wolfpunk]

Here is a little pen and paper random dungeon generator that I came up with one evening. Works well when you don't have a computer handy. If I roll a result that causes a conflict in the layout of the dungeon, I just reroll the result.

Used to have rules like this for randomly generated caverns. I even programmed it in qbasic to export a gridded BMP map of the randomly generated cave complex. Perhaps, since I have just cracked open a book to learn C++ in 14 days, I'll make a program to generate dungeons using your rules, for when you do have a computer handy.
