This book is a great addition. Options are optional, and it's great that this book has so many. It really makes customizing a campaign easy. Of you'll like you never use every option, or likely even half of them in a single you play or run, but having them really gives you a great toolbox to use. Some people are finicky about house rules, so having an official batch of "house rules" to choose from is nice for people who prefer to stick to official products. No book is perfect, but being this book isn't really being forced on anyone (of course I suppose none of the supplements are), and that is a giant bag of options that you can pick and choose from to enhance the game, for those who'd like it enhanced, I give this product 5 stars, especially if I am comparing it to the usefulness of the average Pathfinder product.
