I don't think I ever met him. I may have seen him, but I'm sure we were never formally introduced. But there is a Gary Gygax hole in my universe.
I have to admit that the Gygax story coming to mind now is the one Lee Gold told me about how he took maximum boggle damage on finding out when they spoke on the phone that she was a woman.
This is my favorite tribute so far: Order of the Stick.
