We (the USA) already restrict certain things based on age. You can't vote until you are 18. You can't drive until you are 16. You can't drink until you are 21. You can't serve in the military until you are 17?. You can't work full time until you are 18. I don't think that anyone is going to propose letting a 5 year old, vote, drink alcohol, drive or work full 40 house a week killing people in the military. If we can restrict all of these things based on age why not restrict sales of games. Unless I am mistaken the law didn't restrict minors from owning or playing the games. If parents want to allow their children to play the games they should be allowed to. Just like parents can (or should be able to) let their children operate a vehicle on private property. Children are not first class citizens. They shouldn't be first class citizens. Restricting sales of violent games, alcohol, pornography, or tobacco should be alright.
