I've DM'ed countless people through countless campaigns for many years. And although my playing stopped, my love for the game that Gary made never has.
I have all of my original books, many of the modules, and picked up the 2nd edition just to check it out many years ago. I have my dice stowed away - along with plenty of memories. I don't know how many hours I spent in middle school, high school, college, and after college playing Dungeons & Dragons. The adventures and places in my imagination that I visited will never go away.
Whether it be the halls of Valhalla, the caverns of Arcadia, the cogs of Nirvana, the black hills of Hades, or just plain ol' heaven - take care and happy adventuring, Mr. Gygax.
