I'm 28 and still game quite regularly. I play WoW usually a few hours a night. I get home about 6:30, play with my daughter until she goes to bed, hang out with the wife until she goes to bed, then play WoW until midnight or so. However, during the weekends i play maybe an hour a day, and there are some weeknights i don't play at all.
My wife and i both took vacation the week of memorial day, and over the course of 9 days off I think I played WoW for a total of 6 hours. I guess during the week when working I play games to pass waking hours as quickly as possible so I can get to the good stuff, like playing with my daughter and hanging out with wife/friends/family
