The really interesting stuff about virtuality is what you can measure with it. Because what you can measure in virtuality is everything. Every single thing that every single person who's ever played in a game has ever done can be measured.

Video games are a special kind of play, but at root, they're about the same things as other games: embracing particular rules and restrictions in order to develop skills and experience rewards. When a game is well-designed, it's the balance between these factors that engages people on a fundamental level.

In classrooms full of students who range from brilliant to sullen disaffection, it's games - and often games alone - that I've seen engage every single person in the room. For some, the right kind of play can spell the difference between becoming part of something, and the lifelong feeling that they're not meant to take part.
