The book is focused heavily around the PFRPG "host" campaign, with no clear instructions on how to extrapolate for other campaigns (we use the 3.0 Forgotten Realms setting). So in the end, most of this book is filler and not really very useful. Even the second printing tied the book more closely with the "home team" setting.
What little can be gleaned from the book is helpful, but it's not worth the hardcover price if your campaign is something other than the generic one sponsored by Pathfinder. I wonder why it is, that almost every "host" campaign seems like a patchwork quilt of several others, with most of the interesting stuff left out?
