The Supreme Court will decide whether California can ban the selling of violent video games to kids.
California governor Arnold Schwarzenegger signed the ban into law in 2005, but it never took effect.
The law would have made it illegal to sell violent video game to minors.
"We have a responsibility to our kids and our communities to protect against the effects of games that depict ultra-violent actions, just as we already do with movies," Schwarzenegger said.
A federal court blocked the law, saying there's no solid research to prove a connection between violent video games and psychological harm.
Critics say parents, not the government, should decide what games kids play, but supporters point to some studies linking violent games with aggressive behavior.
The high court will hear the case this fall.
