While I own the 1st ed Werewolf: The Forsaken game and some supplements, I never had much chance to play. I did like the basic concept though, so I picked up 2nd ed. with hopes that it would fit my normal roleplaying group. I was not disappointed, the GMC rules make the game crunchier, while still maintaining a focus on narrative play. The focus on the consequences of being a raging monster and apex predator allow for stories of personal horror that fit my storytelling style well.
My main complaint is with the organization and layout. The book is laid out in possibly the most confusing possible way for a reader who is coming in fresh (ie. not being familiar with 1st ed.). The chapter order is bizarre, leading with Auspices makes little sense when you need to establish what the Uratha are and how they fit in the world, which is covered in chapter 2. Jargon is frequently used before it's defined and often in ways where the meaning cannot be derived from context. It was frustrating to have to go back and reread sections of the book that made little sense without the knowledge from later in the book. It feels disorganized and confusing. Which is unfortunate, as the rules themselves are very good if you can piece them together.
The setting material is solid, painting a picture of a world of often malevolent animist-spirits that have to be handled by the Uratha before they get out of hand. The addition of the idigam to the setting is interesting, but takes up a large amount of space for an antagonist that seems geared towards an experienced and jaded W:tF group. The idigam take up 33 pages while the Pure, Spirits, Shartha, Humans and Claimed combined only get 12 pages. This suggests that the idigam are the primary opponent of the Uratha instead of the spirits and claimed that the Tribes chapter says are the most common prey.
Overall, the new edition is an improvement over the previous edition and the book is written to appeal to players who are already familiar with the game and the setting, but players and storytellers who are new to W:tF may struggle with some of the design choices that were made.
