I really love this setting builder for its elegant simplicity and nice physicality. In a couple rolls of 6d6 across a paper towel and an hour I made a little map of a peninsula and an island I can explore further with other games that need some kind of location seed. The prompts are excellent because they all contain a simple question that leads to future storytelling, both within the session and in other games.
Well worth the price.
(I am weirdly tempted to use this to replan my Animal Crossing island too.)
