Do violent games have a bad effect on todays youth?

I think that violent games do have a bad effect on teenagers because it makes them want to play them 24/7. Violent games can make young people stressed when they lose it also makes them anti-social because they enjoy playing it too much. I think that violent video games make people more agressive and make them generally more angry. Other people think that violent games dont make young people more agressive and that it's not the games faults because they have age rating for a reason!
