I've expressed my admiration for Simon Washbourne as a game designer on this blog before. I have just run across the single best quote about him I have ever heard. (And perhaps the best quote ever for anything.) It was made by Vargold (Rob Barrett) in an RPG.net discussion about Supers! Red.
"Simon Washbourne craps better games on a monthly basis than most people who slave over rules for years."
You can find more of Rob's writing at his blog Vargold: The Wolf Time
