I dislike X-Boxes/Playstations/Computers for children a. lot. My own would spend days at a time on the PlayStation. They'd get up and go downstairs and turn it on when they should have been getting ready for school. They never spent any time doing anything else. My older one stopped reading.
I decided that there was no possible benefit to this, and attempting to tell them to stop didn't work. They did the same thing: "I was only helping him." (Some games are for one player, and others are for two players.) They always had some kind of argument, and sometimes I'd look up and realize someone was playing the PlayStation and "misunderstood" that it wasn't their time to play.
I decided there was no point in getting into a battle over something so obvious, so I simply took the PlayStation away.
The fear I had was of the kid tethered to the computer or PlayStation, with no visible other life. Or no ability to formulate other ways to pass the time. The computer game/PlayStation leaves absolutely no room for imagination at all.
They protested and whined. Then my oldest renewed his passion for manga books and began reading voraciously again. Ranma1/2, Naruto, Bleach and One Piece books -- he began to pester me to go to the library and get more. I had the pleasure of not being able to afford to keep up with my child's book habits! He has developed an interest in cooking. My youngest one started drawing pictures. He looks at books and has been trying to learn the letters. And doing other things has stopped being a way to pass the time until they can get back on the computer.
They ask me when they will get the PlayStation back. My answer is "Never." My son goes over to friends houses to play and I know that they play the games over there. That's fine.
Children will always argue the rules. I don't let my kids on the computer because they end up downloading tracking cookies, adware and viruses by mistake. It's the same problem as with the PlayStation, too, as far as opportunities for imaginative play and doing things that require any kind of thought and planning. The only solution is to take the games away and lock them up.
Some people might protest that that's mean and unfair. But our job is to guide our children and to raise them right, not to be their best friends. If we can't do this little thing that will make them mad when doing what they want is so damaging (even if because it seems to be "addictive" and fosters and encourages conflict between parents and children, even if it doesn't suck the very life out of a child's day) how will we be able to stop them when they're teenagers from going to a friend's house when they swear the parents are home when you know the parents are actually planning to be out of town?
