We discussed this in english class a few weeks ago.

I play video games, mostly Zelda, and I am not a violent person. Although I don't play the kind of video games where you go shooting everyone...I hate blood and gore.
My opinion is that it could influence violence in young children. If they can be convinced that a fat man goes down their chimneys at night and leaves presents, then they can be convinced that a person's life can be recovered with the press of a re-set button. But as you get older, you learn to tell the difference between reality and fiction, and it is not a danger anymore. And I sure hope that parents are now keeping their kids away from violence.

So I cannot say for sure if they do or do not...because more mature people do not seem like the kind of people who will become violent because of a video game, but for some people that is different.
