A watchdog group says video games that have players shoot rival gang members, watch bare-breasted women and recreate JFK's assassination should be kept away from children.
The National Institute on Media and the Family is urging the industry to educate parents about ratings. It's also asking retailers not to sell such games to young teens.
The group's president says the games keep "pushing the envelope."
Among those listed as the worst games of the year -- "Grand Theft Auto: San Andreas." Players rack up points by gunning down police, committing carjackings and burglarizing homes.
A video game trade association says its games carry appropriate ratings, such as "M" for mature. The group's president says kids get the games from adults -- calling that a "failure of parenting" and not the industry's fault.
