Jesse Schell, an assistant professor at carnegie mellon university gave a mind-melting seminar entitled "Visions of the Gamepocalypse" at the Long Now Foundation's SALT series. I highly recommend listening to this podcast (and all other SALT podcasts for that matter), as he is a really energetic speaker and lays out a pretty convincing description about how games are going to become integrated into every part of our lives. The seminar is a bit long though (still highly recommended), so for those ADHD folks out there, here is a snippet of a different talk that gives a decent summary of his basic idea:
In case you're not interested in watching or listening to either, his basic point is that wi-fi and sensors of all kinds are becoming extremely cheap and abundant, and that combination allows you to turn everything into a game. In this case everything mainly involves things related to a consumer society, though the government could get involved as well. I don't think he talked about the possibility for your parents/spouse/family to turn your life into a game, but that seems plausible..."mow the lawn and you'll get a power-up" "wash the dishes or I'll cast a level three polymorph spell on you".
