About three years ago, I asked about folks doing something like the One-Page Dungeon Contest for GURPS adventures. I got no takers. Regardless, I'll ask again: would folks be interested in doing something like this for GURPS? They could be for any of the sub-lines—Dungeon Fantasy, Action, Monster Hunters, After the End—or for none of them. This is GURPS, after all. As proof-of-concept examples, I offer up:
The Demons Beneath the Town
The Haunted Village Crypt
Lair of the Frogmen
I had to cheat on the one-page thing a bit, putting stat blocks over on the GURPS Repository. But you get the idea.
