My only knock I can give him is he is responsible for the original Paranoia roleplaying game. Fucking hate that game. But, being a wargame designer first, maybe it his middle-finger to the roleplaying hobby?
There are further articles (and books) he has written on gaming on the site and they all are thoughtful and steeped with actual experience in the whole hobby. I recommend any fanatic gamer/wargamer read everything he has on his site.
