I'm not exactly an OG — never played Chainmail, but I still have my brown book/white book rules around somewhere, along with the old blue box set and its rotting dice.
I've commented before on my strong suspicion that spec fic is losing a generation of writers to MMORPGs. I wonder how big a generation of writers have their roots in the fantasy RPG movement that Gygax launched. And of course those two gaming trends are strongly linked, so perhaps it's an averaging effect.
Anyway, rest in peace, Mr. Gygax. You missed your last saving throw.
