Sad news. I kinda' wonder how long Dave Arneson (the other co-creator of D&D) will be around--I saw him a year or two, and he looked a LOT older than his actual age of 60:
I figured he was in his 80s, at least. After I looked him up on Wikipedia and saw his real age, I mentioned it to my then-boss, who had also met him at the D&D World Game Day where Arneson was a "special guest" (along with Larry Elmore and others). My boss was surprised and a little disturbed, since Arneson was only a decade older than him.
Too bad there's no Raise Dead in the real world. :-(
