I just found this today and had to pick it up immediately!
I specifically like the section in "Building the world" where you say: "You’re a human who transforms into an animal, or an animal that transforms into a human. This animal is usually, but not always, a wolf."
That reminds me of the Changing Breeds book from Werewolf the Apocalypse and gives me so much flexibility in how to handle my story. Most of the time, I want to be a wolf but there will be times where I want to be a bear or a fox or a tiger.
Thank you for adding that into your game. Can't wait to dig in!
