My children used to play Mario brothers,Donkey Kong,Centapede,Frogger.But if their friends brought their video games from home I examined them thorougly.My son had a friend who did that reguarly.He brought over video games I would not allow.I don't know if he thought I had "stupid" tattooed on my forehead.Many times I had to send the kid home to take back the inappropriate game.To this day my kids are glad I did that.They respect me.They had a good set of morals and values set before them.
