The nature of dungeons is a theme I spend much time pondering about. These are my latests ideas: The dungeon as the antimatter open air village.
Excellent post! Thanks for linking to the Hidden Shrine of Setebos—I’m reading through it now, it looks like a really excellent adventure.
It’s really interesting to me that there’s like this spectrum between a realistic space that is designed to be somewhere a person could live and a game space that’s designed to be fun to dungeon-crawl.
