I am new to GMing (or, playing the Keeper in this book), but I have played roleplaying games for about 13+ years. I've been intimidated by the role, but I picked this game to run because of my confidence with tropes and my love for shows like Buffy the Vampire Slayer, Angel, Supernatural, etc. I've ran three sessions so far and LOVE it.
The book says to be a fan of your hunters. I absolutely am. I really love the mystery arc worksheet the game provides and how to lay out the story with people, places, and a timeline. Everyone has their motivations and you, as the Keeper, get to be surprised and captivated by how your players solve and interact with the mystery and its components.
I can't recommend this game enough. It's so fun to run and it's fun to play. The system is great (based off the Apocalypse World 2d6 mechanics/moves) and there's countless resources out there to draw inspiration from. I actually used the example mystery from the book for our first game and found it enjoyable and successful.
