Too bad. People like him and Gary gave fantastic creative input that thousands of players enjoyed and expanded on.
It's just a a few weeks since Keith "Doc" Herber, famous from Call of Cthulhu roleplaying passed away as well. He had just made a come back to the playing field with the new publisher Miskatonic River. He managed to check out on Friday the 13th though, very stylish when your in the horror business...
