I have this really hectic schedule in the week days so I don't play video games in the week days at all. But week ends, they are meant for gaming when it comes to me. I play for, like, ten straight hours on week ends. Most of the times, I call my friends or cousins over to my place and we go multiplayer. As far as the seasons are concerned, I don't think they effect me much. I play as much in the summers as I do in the winters with the same schedule, no gaming on week days and "only" gaming on week ends. I don't know if ten straight hours is common or extraordinary, but if its common, its only because of my eye site. My head starts to hurt really bad when I stick my eyes on the T.V screen for more than nine hours, especially while playing games which use first person camera.
