I find the transcendental nature of game playing fascinating. The ease with which people can be transported out of their bodies, overriding time, meals, appointments, social interaction tells me that this must be a significant phenomenon. As someone half a step from OCD, I have to keep such things at arms length apart from the occasional 20 hour Civilisation session. The fact that books, music, art, films, so rarely grip us in this way is not necessarily a positive thing, but it is important.
