When I talk about a GM book I was thinking of something that would help GMs structure/flesh out runs, on the go matrix networks or security setups, maps for common locations, goons and prime runners, reward guidelines, inspiration for runs, themes, overarching goals, tips&tricks and of course a run or two to start you out.
Well they have that stuff. But it's spread over 10 books. Alot of it is in either the Runner's Toolbox or this upcoming starter set.
I know your answer will be "Well I want it all in one book for ease of use"
To where business people go "That's nice but we'd REALLY rather sell you 10 books than one".
You can't blame them for wanting to make money. It's how they feed their kids and fund their own toys. Having it in 10 books means we get that much more of each thing you listed. Instead of each thing you listed getting 1/10th of a book.
