My group and I adopted many things in this book. Its well written an dmany of the vaugely worded systems in the Core book are expanded or explained in ways that make it easy to think outside the box. The biggest being the Humanity track. There are some grammer things that could have used another lookthrough or two, but they are easy to look over. While we aren't using everything in the book, there is so much here that helps with running a chronicle!
