Yeah, Peterson's books are required reading for anyone who wants to understand where D&D came from. I think understanding the history of D&D is pretty crucial to understanding why and how to play D&D even today, half a century later. Peterson's "The Elusive Shift" gos into some theory of role-playing games from the 80's which is still as true today as it was then.
