I've seen that before, but the thing that really amuses me about it is that Dark Dungeons is the name of a rather fine RPG: http://www.gratisgames.webspace.virginmedia.com/darkdungeons... I'm about 95% sure the game is named after the comic, but I don't know for sure. Maybe I should ask the creator some day. :)
Thanks for pointing this out. I had a look and the rulebook starts with an adventure featuring... Black Leaf, the thief. I think that's a definite clue, innit :)
Wow, I've got all my D&D rulebooks, but it is kind of nice to see them all laid out in one place; the optional weapon proficiency rules and PC Mystic rules are both in a book that has a bunch of optional rules.
