Fate's guidebook may perhaps be the most needed supplement to the New Gods of Mankind franchise as the first book while introducing an excellent premise and doing a lot for the world building left a lot to be desired when it comes to ideas for what to run as a storyteller. Thankfully this book helps with making it simpler to ponder plot ideas for the game. It adds more to the world building and helps exploring different things one can do with the player pantheon so this book is definately a necessary reed.
