No, however, I'm going to have to read that as it sounds pretty interesting! The idea came out of a "What would be fun, get people exercise, and allow us to interact with others, make use of our hobbies - and add excitement to our lives?"
Also "This is not a Game" by Walter Jon Williams. The main character designs games like this. Then since it's fiction winds up involved in the real thing, of course. I liked it, and there's a sequel coming out soon too.
