Assuming that was not a rhetorical question . . .
I asked him once: If someone bought D&D and let him run it again, would he be interested in writing for it again? He said he'd think about it, by which I think he meant yes, if I was serious and the offer was right and he had creative freedom, but no if I was just trying to create controversy.
Sadly, my friends and I don't have $30 m. (Doesn't anybody game at Google?! Then start a darn gaming club and buy D&D with 10 of your friends!

)
But I don't think he wants to work full time anymore.
