When you first started talking about r-maps months (years?) ago here on G+ I was skeptical, plus it looked like a ton of work. Turns out, they flow together when you get everyone at the table involved and you ask the players questions.

Using their answers (or modified answers that fit the big picture and setting) was a relief. Less work for me, buy-in for them. Plus it was fun for everyone. I think I get games like Microscope now.
