Some fun things are in here that add depth to designing the wilderness in your campaign setting. Particularly the method of communally drawing the world map is something I’ve used in many of my games. However the format of many rollable tables and more complexity of rules clashes with the spirit of Dungeonworld's impromptu rules-lite feel. You want to give the GM just enough to help them tell a story, not bury your nose in dozens of pages of tables. Some of the choices are also baffling, like rollable tables or moves where nothing happens: you can roll for a hireling's background and get "unremarkable" or roll to gather hirelings and have no one show up. This is overtly contrary to the core of Dungeonworld that every roll makes something happen. Also the name lists in the back are great, but I hope you like Hungarian, Yoruban, Finnish, and Indonesian names because that's all you get. Why they don't have lists of more standard easily pronounceable names is beyond me. It's a shame for a supplement made for Dungeonworld with some neat ideas that you have to fight it's design to run a game as instructed by the Dungeonworld rules.
