Edit: After over a year of having purchased this.
I have already expressed a written, detailed review to the authors (personally) several weeks ago. I will keep my detailed thoughts with them, in the hope that revisions will be released at some point.
If you are predominantly a player, and have already bought this - read chapter 7 first!
I don't mean to be too hard on the authors' effort, because MT Black and co. absolutely should be absolutely be commended for their work here. All the options (especially races and archetypes) presented here tell very compelling stories (especially with something like the Cleric - Prophecy Domain). At the end of the day, if you have a group that cares less for mechanical exploitation and more for storytelling, then this is a great supplement to have!
In short, I like 60-70% of the book (which is good!). The races chapter, in particular, is my favorite! I still respect the work that was put into this (as should everyone else).
