My oldest has video games. My ex was hooked on them, and he had them in the house, so ds1 started playing them. DS1 has never let them push out all his other activities - except for a couple days when he gets a new game - so I don't let it stress me very much. If he's playing a video game, and a friend wants him to come out and toss a frisbee or practice gymnastics, he does that. He'll drop the game controller to hang out with a friend outside or even to play with his younger siblings. He's still at least as likely to pick up a pencil and sketch, or pick up his juggling gear, as he is to play a video game. So...not a huge deal here. We do have to kick him off the games to do chores or homework sometimes...but we also have to tell him to put down his guitar, get off the phone, stop his living room workout, put away his juggling clubs, etc. etc.
We haven't really enforced any time limits for a long time, because he self-regulates pretty well. His consoles are also hooked up to the only tv, so he can't play if the family is watching a movie, or if I'm practicing for choir (I run my practice CD through the DVD player). So, there are a lot of built-in controls.
That said...they're certainly not necessary, in any way. I can't imagine why anyone would criticize someone for not having them. I've seen a lot of ds1's friends get seriously sucked into the games (like come home and play them until bedtime, with a short break for dinner), and they do make me a little nervous. I'm sure we'd change things if they became a problem for ds1.
I don't get why people are so invested in what other people have in place in the way of rules.
One thing that makes me sad is thinking back to when ds1 was little. I can remember coming home from work on a really nice day, and ds1, my nephew (my sister was his babysitter), and 3 of their friends were in my nephew's room. DS1 and my nephew were playing a game, and the other 3 were just watching. I asked ds1 if he and his friends wanted to go to the park, and all 5 of them jumped up and practically cheered. They didn't even really want to play the video game...they'd been chased off into the bedroom and didn't really have anything else to do. We walked to the park, and they spent about an hour and a half playing physically and showing off their skills for me. When I got back, my sister and the other moms told me they really appreciated me taking the kids, and that I was "crazy" to do it. *sigh*
