This is pretty ridiculous overall, and I'm not sure why anyone would want to watch any of this video. However, thousands and thousands of people did, so obviously I don't have my finger on the pulse of what is hot on the streets these days. Ok, I could see someone setting this TEN HOUR "event" up on a TV if they didn't have a fireplace in their house, or better, if they had a fireplace and no fire going. You could set a small screen in the hearth and let this run, and people would chuckle at it occasionally. I suppose that would be worthwhile.
Maybe.
The basic deal is exactly what it sounds like: the director of Overwatch, Jeff Kaplan sits in front of a fire, near motionless, for ten hours.
I can't really set it up better than that. Enjoy.
