From the desk of science fiction writer and wargamer Jon Mollison comes this penetrating analysis of dungeon design. It some ways it goes over some well-worn ground, the tension between the "Mythic Underworld" model and the "Gygaxian Naturalist" model of worldbuilding; but Jon really takes it to a higher level (no pun intended) with a surprising argument that the Mythic Underworld is the most realistic dungeon of all. Highly recommended.
