Many times has it been seen that small children are playing violent video games, such as 'Halo', or 'Call of Duty'. These games have a rating of 'M' for Mature, stating that they are appropriate for anyone the ages of seventeen or older. Many times has it been seen that in stores like 'Gamestop' that parents are bringing their children who are under the age of thirteen, and even ten, to buy these games. The employees are required to say why it is 'M', but not enforce the ratings of them.The children seen playing these games tend to be more spoiled, more obnoxious, and more disrespectful than children who do not play these games. The children have also been seen swearing, both online and to their parents, due to playing the game with the intended audience of people seventeen+ years of age.
