This book is a work of blood, sweat, and unadulterated awesome. I had so much fun DMing this system for a group of friends that we made it our main game feature, its easy to use and learn without the downside of a lack luster system that fails to sate the needs of the party.
The book gave me everything I needed to build a flexible game, cool tables, rules that make sense!, and endless possibilities to kick evil in the gonads and say "NOT THIS TUESDAY DEMONS, ITS MY DAY OFF!"
The cover says it all folks and if it fails to give you thrills then I think its time to hang up your dice bag because you are looking at the holy grail of games. P.S. Don't tell the Vatican, they are still looking for it!
