An anonymous reader writes "IGN has an article up looking at the impact of violent videogames. It discusses some of the rationale on the gaming industry side for having violent images in their games, and the reactions from politics and lawmakers to these games."
From the article: "Despite the large body of evidence that supports a link between playing violent videogames and aggression, lawmakers still have a difficult time convincing the courts that they should be removed from children's hands. One of the reasons for this is that most of the work done is correlational studies which look for a link between two factors. That is, if we see an increase in violent videogame play, is there also an increase in violent behavior?"
