I love the writing and layout of the rules system. My only complaint has to do with the pdf. It's not laid out or formatted very well. To go through it's 120 pages you hasve to scroll, there are no bookmarks. so if you've got the pdf pulled up it's a bit of a PITA to get to a particular page you're searching for.Fix the pdf or add proper bookmarks and it'd be a 5 out of 5 for me. But as is, the pdf isn't nearly as useful as the book is.
