I like the comparison to Story Games actually. As a semi-outsider in multiple communities I find it endlessly hilarious to watch groups of my friends talk about how each others shit is all ideological, as though that was a bad thing, and then defend their own incoherent shit with fire, as though that were not ideological.

But aside from that, I gotta go with the OP. I found the book useful back when I was looking to start a retro clone game.
