From 2006-2015, Greg participated in a Q&A thread over on the Acaeum, 107 posts total. There are lots of great posts worth reading there, but given the focus of my blog, I'd like to highlight the first one, a fun story about how he may have received the first ever sold copy of OD&D ---
"I'm mainly a Chaosium guy, of course, but I'd like to share one tale about D&D to start, from WAY back when.
I used to work for Bergamot Brass Works, a belt buckle company out of Lake Geneva, WI after high school. Real hippy job. I'd take buckles, hitch hike around and sell them to shops, etc. After a while, though, I moved to California. My friend of the time remained there, selling buckles (we were called Buckle-itis).
Through various circumstances I'd decided to publish my first boardgame, White Bear & Red Moon, on my own. As I was finishing up work on it, I got a package in the mail from my old partner Jeff. His cover letter swaid, "I was picking up my catalogues from the printer the other day and there was this guy waiting for his stuff. I asked what it was, and he said it was a fantasy game. I said, 'Hey, my buddy in California is doing one too! Can I buy one from ya?'"
Of course the guy was happy to, and so Jeff sent me this strange little booklet called Dungeons & Dragons.
Later on I thought, "Heck, I wonder if that was the first one ever sold?" Well, I asked Gary Gygax if he remembered this incident and he did, and confirmed that it was the first one ever sold.
MAN, do I ever now wish that I'd not lent it to my DM and never gotten it back!!"
