I just wanted to say that I participated in this event, and it was so much fun! Brandon put up with a lot of crazy ideas. He wrote a great start to a story, we met his family and even got to talk to his wife Emily for a bit. I think it raised about $700 for Worldbuilders, which was the purpose of the event.
I watched the whole thing too. I decided I'd only watch a couple of hours because it started at 9 my time but I stayed up until gone 2 because it was so engrossing I think they recorded the whole thing if people are interested in watching.
