Well, I'm 27, married with 2 children, gainfully employed, have a house, and hold a B.S. I have entertained a consistent gaming hobby since childhood.
How do I, or anyone else, find time for it? It's really not hard. It's up to you how you spend your leisure time. A lot of people spend it staring at whatever dreck is on TV. How do most people with jobs and families find time for American Idol and whatever else is popular on TV. I mean, if Nielssen statistics are to be believed, the average american spends some 4+ hours in front of the TV per day. That's a lot of time. So, it's easy to fit in gaming in place of some of it.
Incidentally, this is also the reason I don't buy it when I hear someone say "Gee, I would sure like to read more, but I just don't have the time." They could just turn off the TV if they really wanted to read. It's up to you how you spend your leisure time. But no, they instead back-handedly imply that I'm lazy and lead an easy life because I make time to read.
