Reader Saskia, aka NagatoPyon, has done the world a service and filled the marketplace gap once clearly labelled as "NEEDS MONKEY ISLAND BOARD GAME".
The game she's made involves Murray the skull, has devil chickens, the Tri-Islands area and cannibals. Just about everything you'd want, basically.
What's more, she's made the files necessary to play it yourself publicly available, so you can grab them below and try it for yourself.
