and this is what they said.

"Sure, some children displayed a playful aggressiveness after hours spent with a violent game, but this was no different than what children experience after seeing a martial arts action movie."

"Some researchers, including the Harvard psychologists, even suggest that video games have a positive effect on the brain. Steven Johnson explores this concept in his book Everything Bad is Good for You: How Today's Popular Culture is Actually Making Us Smarter."
