- Central Casting: Dungeons--Robert Sassone's masterpiece--if we can use that word here--presents 180 pages of dungeon-creating tables. There are lots of dungeon room ideas, as well as a lot of detain, even if you don't use the random-generation approach. This is the one dungeon book I would take with me on a spaceflight, lifeboat, or desert isle.Engineering Dungeons is similar and more recent, but also drier and lighter on content.
- Dungeon Builder's Guidebook--This little volume--from the AD&D 2e era--is a nice companion to Central Casting: Dungeons. It is not as comprehensive or detailed, but it includes some weirder dungeon variations (e.g. underwater, aerial, and interdimensional).
- Dungeoncraft-- A D&D 3.x e product from Fantasy Flight Games (part of their Legends & Lairs series). I nice collection of dungeon ideas, mixed in with the obligatory prestige classes.
- Dungeonscape--This Wizards of the Coast publication was intended for D&D 3.5e. The content is uneven and a bit thin but it does have some groovy ideas and interesting magic items. If you combine this with the Dungeoneer's Survival Guide, you end up with something kind of decent.
- Tome of Adventure Design--This Frog God Games product is still in print and is a go-to book for me. Lots and lots of excellent tables. They are not all dungeon-related but there is enough dungeon goodies to put this on the list (I use this book a lot...more often than any other book on the list). Kellri's Encounter Reference, available for free as a PDF and is excellent. Michael Curtis' The Dungeon Alphabet is a fun book with some great off-the-wall creative and useful ideas, but is lighter on content. If you are looking for dungeon tables, check out The Dungeon Dozen (blog) and also my own blog page, Megadungeon Links II: Maps, Tables, Generators.
