I'm honestly not sure why this product got anything higher than a 3 Star review. The material is very dry and uninformative pretty much across the board. The topics are very brief, not really adding anything to the game, except for using a lot of words to effectively say nothing. It feels like it was really rushed, and really that is about it.
I honestly can not think of a single things I'd use from this book. Even the section talking about some diffrent concepts for the changes the had considered for the V20 line itself don't actually go into any actual depth. While the book does cover everything in it's description, it does NOT do so in a fashoin that allows it to be useful at the table, and just leaves the reader wondering, why even bother?
