You just got a new RPG. Let's call it 'Bing the RPG'. New setting, new rules, that sort of thing. At the end of the book (just before the crappy index) is the GM advice section. What do you want this section to say? I'm curious about what people look for in the GM sections. Do you want some plot hooks and campaign ideas? Or do you want indepth discussion of the themes and how they can be brought into the game? Or maybe rules notes?
I know most GM sections include a bit of everything, but what would you prefer as the focus?
