Yesterday Dungeons and Dragons creator
Gary Gygax passed on from this life to the next and while I'm wasn't the biggest D&D geek in the world it's hard to really state his impact on the games industry. Gary Gygax was the guy who created the concept of the role playing game and made it popular and with it influenced countless generations of game designers including Richard Garriot and John Carmack. Without Gary Gygax the video game industry wouldn't be where it is today and he will be sorely missed.
