I'm really conflicted on what to rate this product. For the price to crunch value, I'd have to say a 2 (maybe even a 1). But I really like the rules for AIs and for that I'd give it a 4 or 5.
I have a major gripe with one thing, though. The terrible excuse for a a table of contents and a complete lack of an Index! The rules for creating an AI starts on page 145, which doesn't even show up in the Table of Contents. Instead, it is buried in a section called "Principles of Insanity". WTF? How are you supposed to know where this is short of memorizing it or looking at every single page?!? If there was a good Index, I'd forgive this, but I have to reduce the rating to a 2 instead.
There is some useful information here, but why is the ToC so terrible? For a premium priced PDF we should get a good ToC AND a good Index. There are apps that will build both of those for you, and this book really needs it.
