In addition to all players rolling a d6, roll a d30 for the game. You only win if your roll is the highest out of the players AND higher than the d30 result. Otherwise, you all die.
And no namby-pamby re-rolls - in the event of a tie, everyone dies regardless.
LOL. I like it.
Imma get some specialized d6's with various treasures on the faces and nice big, firey red d30 for the game. Maybe I'll even print out a small play mat witht wisty dungeon images to roll on. I'll call it "Dungeon Quest Express."
