This video is a presentation by Jesse Schell ex imageneer at disney studios and Carnegie Mellon professor. He holds a lecture on reality layers in games at the DICE 2010. Schell gives an insight on how facebook games got so successful  and why especially you are playing mafia wars or farmville. He draws a vison of the future of gaming which quickly turns out to be a vision of our lives. I really advise everyone to take 28 minutes of your precious time and watch this video, since i can only agree with what G4tv.com says: This is mindblowing, enjoy! via nerdcore
