If you’re interested in the history of D&D, one of your best resources is the long-running enworld “Ask Gary Gygax” threads. From 2002 to 2008, Gary Gygax answered a heck of a lot of fan questions. Unfortunately, there are over 500 pages in the Ask Gary threads, so if you’re looking for a specific anecdote, you have a lot of message board pages to click through.
For your Ctl-Effin’ convenience, I’ve compiled all of “Col. Pladoh’s” Ask Gary message board posts onto one (long) page.
Note: I edited Gary’s enworld posts into a book, Cheers Gary, for the Gygax Memorial Fund. At the request of the Gygax Memorial fund, I have removed this complete transcript of the Enworld Gygax Q&A. If you want to read his opinions, you’ll have to read them on enworld or await a second edition of Cheers Gary. I wish the Fund the best and hope they get the second edition printed soon.
