I recently learned that Tracy & Curtis Hickman wrote a GM-focused... tool set? Thingy? (Title in CW.)

And just now learned that it has a m*d-libs type story/plot generator.

That *alone* sounds worth it to me. Mainly because, well, I'm sort of stuck in my own head most of the time; certain synaptic pathways have gotten worn down to bedrock in my 45 years.
