We've had a Wii for a fortnight now: every day I play it, the game gets incorporated into my dreams.
Last night: The rhythm heaven game became a 'clock' for the running of society - if I didn't hit the second hand at the exact time a bit of the world exploded - I realised the futility of top-down clock keeping and shared the responsibilities. After that was decentralised I had to cut down - like in Zelda - all the centralists that wanted to run the clock themselves fearing others incapable.
