Yes, from what i understand TSR was interested in republishing Wormy and they got into a bitter dispute over that, and he left, angrily, wanting nothing to do with the fantasy business anymore. I tend to think he was a purist, and thought that the business of fantasy gaming wasn't pure anymore, it had already sold out to stockholders and he wanted nothing to do with that. He went on to become a taxi driver, and was rediscovered when someone - who completely didn't know who he was, but was writing a piece on cab driver, published an interview with a picture. That's in 2002, and the Internet was already pretty big, and people immediately recognized him and some started trying to get in touch with him. Many tried to reconcile him with the fantasy business but he was adamant on not doing it. In his final years, though, after the cab company he worked for went under, hewas finally ready to return to the fantasy business, but cancer got him 3 weeks before he would appear on a conference where he would talk about Wormy and his work and maybe of republishing, or continuing the series.
The world lost an irreplaceable person right then and there, and the fantasy world wept. I didn't know about him, because i never really looked into any of the older editions of D&D. I never got into the original, wasn't born yet, never got into the first AD&D, i wasn't born yet, and i was too young for the 2nd AD&D as well. I caught SOME of the final days of AD&D with Baldur's Gate, Planescape: Torment, Icewind Dale and Pool of Radiance. NEVER saw any 2nd ed material for myself, in person, only in pdf's, and never read anything of the older editions EXCEPT the first monster manual, because it had some very amusing critters that weren't reprinted again (OOTS led me into that...). I only started really playing D&D with 3rd edition - like many here, i suppose - and am very rules dumb towards anything other than it. Never played 4th ED and never will. Didn't like it one bit.
But now i kind of feel like i want to read the older rulebooks, and see what it was like? Just because of the art.
