This idea intrigued me so I began watching a game designer, Jane McGonigal talk about the qualities that gamers possess and how they could possibly turn their enthusiasm, focus, and optimism form the virtual world and somehow translate that into the real world. Fascinating--worth the 15 minutes.
For the record, I am not a gamer, but many of my students are and were also intrigued by her ideas. Additionally, one could argue that it takes a great deal of psychological knowledge to make a satisfying gaming experience. In fact, one could use the video as a point of analysis for psychological concepts (that are mentioned, but not by name). Again, great stuff.
