Your son is 10 how long should he play video games

I have a lot of kids (ages 16, 15, 13, 13, 11, 10, 9, 8, 8, 6, and 4.) and they're all boys. I would consider my wife and I to be good parents and we have no trouble with our sons. My boys all play for around an hour or so on school nights and as long as they want to on the weekend. A lot of people say you should restrict TV, computer use, and video games, but we tried doing that, and it only makes them mad at you. Instead, offer some different ideas, and hang out with them outside. Make them actually want to do something else. It makes the whole family happier.
