I got a copy of Gygax magazine recently and all the fun memories came flooding back. I made life-long friends and thought about things I never would have due to D&D and its decedents.
On the darker side of humanity, D&D also gives a bit of a current lesson to techies in the valley. It is very easy to demonize a group and make quite a bit of cash off it. If you didn't head the lessons of the Tea Party and Occupy, then maybe looking at D&D wouldn't hurt.
"So, what do you do?"
