A group that monitors violent video games is out with its eighth annual report card, which gives some failing grades.

The National Institute on Media and the Family says a segment of the video game field still produces games strictly for their violent content.

Group President Dave Walsh said that's of particular concern for teenage boys, who have easy access to them.

Walsh said the teenage brain is not developed enough to handle the level of violence in games that are so popular with that age group.

The group said in its report that 87 percent of children from fourth to 12th grades play video games, including 96 percent of boys who play regularly.

Walsh refers to the violent games as "killographic," a word based on "pornographic." He said he had to create the word because there is nothing in the American vocabulary that describes "the graphic portrayal of extreme violence" found in some video games.

Still, he said, there has been some progress. He said retailers are committing to do their best to keep violent games out of the hands of children. However, 87 percent of boys said they play "M-rated" games, which are supposed to be for a mature audience only.

Media and the Family says that beside the violence, it is also concerned about large amounts of time in front of a monitor contributes to an obesity problem. The report card gives an F to the video game industry for contributing to the problem.

The game rating system itself got a B, but just a C for efforts to educate parents about what it means.

The group also gave lists of games to avoid and those it suggests for families.
