I am a big fan of Magpie Games, so feel free to tale my review with a grain of salt.
Last Days of Anglekite is a fantastic adventure setting for Dungeon World, full of strange evocative monsters, NPCs, artifacts and locations. In fact, my main complaint is that there is too much going on in this book. Much more than I could fit into a single campaign.
As someone who plays a number of games besides Dungeon World, I would also say that this would be a great campaign for a number of fantasy campaigns. I could definitely see converting it to a certain 5th edition game that is all the rage, or Savage Worlds, or Fate.
Admittedly, the book does not give you a tactical level tour of the world - no town or city maps, for instance - but it does give you a city of demons and another of undead, pan-dimensional slavers, werewolves and vampires, and enough plots and motivations to understand how they all smash together to cause destruction only your heroes can stop.
A great book. Buy it!
