Reduce game ratings to 15

I think many people will agree that a minimum age requirement for new games is too high currently at 18 years of age. This is wrong for many reasons;

1) More people under the age of 18 are more likely to play games such as Call of Duty™ Modern Warfare 3 and Gears of War than many older people as they would be working and have more important things to deal with in their lives.

2) The minimum age requirement uses the excuse of people under the age of 18 will be influenced by the graphical content of the game, however, people who are 15 years old will definitely have common sense and know what is right from wrong whether they are high achievers or not. Schools constantly drill into students what to do and what not to do so a 15 year old is not going to find a weapon seen on MW3 and go and kill many people.
