Without question or doubt, this is the best RP suppliment ever written. It does what no other suppliment does: I inspires the imagination with a whole new realm to role play in. The idea of 1930s hobos secretly being magical defenders of the realm is innovative but the idea that players would want to have a hobo for a character is totally unique.
What I see in reading this, is that the author knows role players and understands them well enough to craft a world that you wouldn't even think is worth playing it.
I actually took the world ideas and played them using D20 modern, but there is nothing wrong with the system the game comes with.
When I urchase a product, I am usually looking for idea, in this book, I found them and the game that followed was fun for everyone.
