How long can kid play violent video games

there really isnt a decided time...... I would say a few hours at a time so he doesent become 100% addicted, to the game. Be sure to just make sure, that he/or she does not start getting the language off of the games, and now with all the saftey in the united states, you can get kicked out of school for having your hands as guns...... so it really all depends on your comfort with it
