The Spawn of Fashan

The Spawn of Fashan was a tabletop role-playing game created by Kirby Lee Davis in the early 1980s. Only about a dozen copies sold, and the game would've vanished into obscurity had not an April Fool's edition of The Dragon decided to publish a review of it. The reviewers could not tell if the game was supposed to be serious or not.

The game's name appeared many times in the classic "Real Men, Real Roleplayers, Loonies, and Munchkins" list, as being the favorite game system for The Loonie.

If you actually want to see what the game's rules were like, an online review is available on RPG.Net. It's not pretty.
