You play amateur detectives in a cozy-fantasy setting. Your band of plucky investigators solves mysteries (quite often, murder mysteries) that crop up with remarkable regularity in the lovely little halfling village you design together.
The real dungeon was the hobby we made along the way. Dungeon crawl your way through half a century of RPG history in this full-scale megadungeon for the DIE RPG by Gareth Hanrahan.
