Here’s a fun one: an automatic dungeon generator that creates not just a map, but also a complete list of encounters for a dungeon based on the parameters you set. The results are surprisingly game-able, in an old-school sort of way! File this one away for the next time you find yourself at the game table woefully unprepared.
No insta-generated dungeon could possibly be worse than a few of the completely-made-up-on-the-spot dungeons I’ve foisted on my players in the past. Of course, cobbling together random monsters and dungeon layouts is a time-honored D&D tradition, and is made easier by the fact that typical D&D dungeons tend not to be marvels of architectural logic. As long as the players think you know what you’re doing, it’s all good.
It would be a fun gaming challenge to auto-generate a half-dozen of these random dungeon maps and then play straight through them as one mega-dungeon, using the listed encounters as written and not worrying about internal consistency. I’d say that has about an equal chance of either being the most entertaining gaming experience of my life, or the experience that finally makes me consign my Dungeon Masters Guide to the flames and take up a normal hobby, like golf or LARPing.by
