If you do not know the game, I would only recommend the game of Pegasus. It is easier for beginners einzusetzten properly based on a number system characters.
If you but a fan of the werewolf game, this game is an absolute must here. It is designed so beautifully. Everything in this game is very well thought out and fits perfectly together. (In other games characters are somehow superfluous or hinder).
There are great suggestions for variations. And it raises a very nice dark mood.
I love it.
