I didn't know much about Gary Gygax except that he created Dungeons and Dragons. I bought a book he wrote about creating fantasy games and read some of it when I was a teenager. But I think I am more cut out to play games than to create them. My creative talents run in a different direction.
The state gave us a floating holiday when Reagan died to mourn the popular president how we saw fit. I wish Massachusetts would declare a day of gaming in memory of Gygax. It cannot be understated how much fun role playing games can be, and how much bonding over shared experiences can happen among people across some stat sheets and dice. My website is named after a character I never would have created if Gary had not popularized roleplaying, so clearly it's left its mark on me.
I can say in all honestly that I think the world would be a better place if more people were involved in role playing.
