controversy in video games

i think one important reason to support it is freedom of choice. If i want to play a game where i go around and kill people in the street for no apparent reason, i have the constitutional right to do so. also People who cannot differentiate between "fantasy" video game world and the real would should not be playing them. I think that most people who cannot differntiate are generally younger which is why there was a rating system created. An example of this would be Grand Theft Auto III, it carries a mature rating so the parents of younger players are "for warned" that the content is questionable, but at the same time Older players can still play.
