The ol' Blue Box was a gift to my brother, that I managed to get after doing his chores. I was in elementary school and didn't understand anything. Then middle school came, along with reading comprehension, and it clicked. Some friends had the 1st edition books, and from there we formed a club.
In ninth grade I wrote pages and pages of adventures for our group. I was the DM, and we played nonstop, except when we played Ultima III, which we also played nonstop. College saw all of us playing more than we studied, but through the gift of D&D, we understood THACO, and therefore, could understand college lectures. During this time there was a lot more adventure writing and some game design. There was also jumping around to other games: Dangerous Journeys, MERP, Rolemaster, Earthdawn, Masquerade, etc. Along with MtG. For all of these, including MtG, I continued to write adventures.
Then we all moved and the gaming world stopped for our cohesive group.
I missed third edition and got married and moved around. I shifted from Florida to Alaska, back to Florida, then to Texas, to Illinois, to California, back to Illinois, then Virginia. And I say this sincerely, in every place I have lived, there has been nothing but kind, open-hearted, caring gamers that are empathetic and honest. And that is every group, sometimes two or three groups. In every state. So either we have the greatest community in the history of mankind, or it turns out, people are really just pretty darn good once you get to know them.
I teach high school and have run a lot of different D&D clubs. And am involved in a campaign with a great group now that plays weekly. (And a different one online that is spotty, but when we're together, it's always fun.)
