It's interesting to me that as the years have passed, I've found myself playing more and yet less at the same time. Managing a 12 hour raid week (three nights, four hours a week) became impossible for me awhile back. Nowadays, I think I raid closer to 9 hours per week, and even that is a lot of time for me. It's not that I don't like the game or playing it any more, it's that I simply have a hard time playing in a way that commits my time for extended periods like that. An hour here and an hour there, not a problem. Four hours in a row is a big problem.
As WoW ages and the players age right alongside it, we'll see more and more of this, so it leads me to ask you -- how much time can you actually spend playing WoW uninterrupted? How much of a day, a week, or a month do you actually spend in Azeroth?
