Really good tool for both GM's and game designers.
There is time for shooting (intuitively) in the dark sky, and time for clear structure. I love how this book presents exact points to pay attention to - and also when and in which cases.
Even more, Russel Brown analyzes how the story is built in four distinctly different rulesets: D&D, DW, Fate and Hillfolk.
... damn, now I want to buy Hillfolk... :)
