I think that a bigger problem may not be just the games, but the entire media as a whole. Any movie I have watched were police officers were in the major plot, it seemed that the bad guy in the end was always the police officer. I can only think of maybe at best three or four movies in the past five years were police officers ever played "good guys". As well I did enjoy playing GTA3 Vice City, however I myself am smart enough to know that I was playing a bad guy, and I don't support criminal activity one bit. The major concern however is that more often younger kids are playing these games, I've heard of kids in Grade 3 playing Grand Theft Auto. At that age I think a child is very impressionable, and the last thing any of us want is for kids to get their values from this game. As well parenting is harder then it was before, even if you ban a game from your house, your kid could just as easily play it at a neighbour's house or a friends house. I think that they should make violent video games illegal to buy for children under the age of 16, as well if parents come into a video game store and ask for a computer game and say its for their 12 year old kid then they shouldn't be allowed to buy it.
Video games should be set at the same standards as movies. I think that a good idea would be to get parents to be to get a license for taking care of kids. Why not, if they expect to have kids the least they should do is learn how to make kids into good citizens.
