I played this a few times in highschool, and loved the bestial nature of it - more fun than Vampire, to be sure. On the other hand, werewolves are a lot less interesting than vampires. White Wolf did a good job of making the werewolf almost as angsty as their vampiric bretheren, but being a heirsuite eco-warrior just isn't as cool.
Basic Premise: How to play a Werewolf in the World of Darkness system.
I played Vampire first, but once I was introduced to Werewolf I never really went back. Werewolves were much more my style than vampires.
This book has everything you need to know to play or run a basic game. It has all of the character creation rules, combat system, and general game play information. There is a lot of story built into the game (the thing that White Wolf really does best) so the world and how it differs from our own is very clear.
As always with White Wolf, the story is far more detailed than any of the rules, so GMs need to be creative and ready to play referee. Never let the rules get in the way of a good story.
Although I've never played the card game this book was set up for, I own this book, as well as the dozens of subsets further exploring each different werewolf pack/sept and their strengths, weaknesses, abilities and proclivities. Great to check out if you are into werewolves! Awesome illustrations too!
