I bought this looking for a little spice to my home game, and due to a curiousity about how exactly devils would go around making deals, and it has drastically improved my game. These contracts forced my players to get further in their character's heads and presented an interesting new type of conflict- Them versus their morality. The provided contract template was wonderful and absolutely stunned my players when I gave it to them, and at that point they were hooked. Beware though! Devils are awfully good at their job, and once you know how to tempt your players, theres a very real chance they'll succumb. And then you have your next storyline as they try to win their souls back.
