Starting Points

Dungeons were the initial focus of RPGs with Dungeons and Dragons, and they are still popular in the 2020's.

Use them solo, put your group through a D&D crawl, go full on OSR megadungeon or repurpose for a more modern take.

For creating generators, Grid Sage Games has a (fairly old) blog post on Procedural Map Generation. And there was a list of resources in a reddit post from 2022.

For a list of (non-random) free map resources there's Dyson's Map Archive.

There are related Dungeon Guides for Fantasy Dungeon Generators and Fantasy Dungeon PDFs & Books.
