Dave Arneson, co-creator of Dungeons and Dragons, has died.
From Ed Grabianowski's post on Robot Viking:
It's tempting to say that Arneson brought the "fluff" to D&D, while Gygax was the "crunch," but that's really too simplistic. It is safe to say that Arneson's ideas on storytelling, experience levels and rules flexibility shaped virtually every aspect of the RPG as an industry and an art form. Yet he never achieved the widespread fame that Gygax did, perhaps because his personality wasn't the kind that drew attention. By most accounts, he was easy-going, good-humored and never took himself too seriously. I've always thought of him as the George Harrison of D&D.
