IOWA STATE (US)—Exposure to violent video games makes kids more aggressive, less caring—regardless of their age, sex, or culture. That’s the conclusion of a study analyzing 130 research reports that included more than 130,000 subjects worldwide.

“We can now say with utmost confidence that regardless of research method—that is experimental, correlational, or longitudinal—and regardless of the cultures tested in this study [East and West], you get the same effects,” says Craig Anderson, Iowa State University Distinguished Professor of Psychology.

“And the effects are that exposure to violent video games increases the likelihood of aggressive behavior in both short-term and long-term contexts. Such exposure also increases aggressive thinking and aggressive affect, and decreases prosocial behavior.”

Techie that I am, im not sure that I want my children to be playing violent video games when their younger. I certainly wouldnt allow my child to play Modern Warfare 2 until they were old enough - old enough potentially being when they are legally allowed to drive.
