I loved every page of this book. Some of it was just the gaming stories, but most of it is due to the ideas spawned from it.
John Wick does a great job in planting campaign seeds to use to screw with (not screw over) the players in your campaign. He describes way to use not only a character's weakness against him; but his strengths as well.
I know I'll be reading this book another time or two (printed for highlighting) to keep these ideas fresh in my mind.
