Violent video games have been a target of controversy for quite some time now. Do they really cause normal kids to transform into something else? Will playing these games make you more aggressive?
Some people say yes, they will cause more aggression and may change kids to commit terrible actions. On the other side of the table, people argue that it does not affect them; these kids were already aggressive to begin with. I think that both sides are right and wrong; the effects that are made depend on the person who plays these games.
Video games can change the behavior of certain people. Young children are an easier target as they like to mimic things they see. It would be wise for parents to restrict their younger children to age-appropriate games. Teenagers and adults, however, will probably not become more aggressive.
Based on my own experience, my behavior has not changed because of violent video games such as first person shooters and horror games. My aggression level is still the same as it was before. I am equally prone to throwing my controller in frustration while playing Mario Kart as I am playing Halo. However, I have become desensitized because of exposure to gore in these games.
The issue of correlation vs. causation applies greatly on this topic. A person who plays violent video games may be more likely to commit a crime, but that doesn't necessarily mean that video games were the cause for these actions. Their own aggressive behavior may have been.
