Senator Leland Yee penned the law, which mandates that retailers restrict sales of violent video games to only those over the age of 18, with games that fall under the definition of "violent" forced to sport an prominent "18" sticker on their packaging.
According to the law, any game that contains "serious injury to human beings in a manner that is especially heinous, atrocious, or cruel" would fall under its jurisdiction.
"This is the same technology the armed forces use to help soldiers kill the enemy," Yee explained to the San Jose Mercury News. "All we're saying is, 'Don't sell it to kids.'"
In his 2007 ruling, Judge Ronald Whyte declared that the law's definition of violence was too broad, noting that it could apply to some classic literature, and questioned the tenuous link between violent video games and violent behavior. Following Whyte's decision, California governor Arnold Schwarzenegger vowed to appeal the ruling.
Various figures, such as Stephen King, have spoken out against the government's attempts to involve itself in the self-regulated video game industry. According to an FTC report, the video game industry's self-mandated ratings system is more effective than that of movies and music.
"What makes me crazy is when politicians take it upon themselves to play surrogate parents," King argued earlier this year. "The results of that are usually disastrous. Not to mention undemocratic."
"I think video game legislation has no place in America," Resistance 2 creative director and Insomniac Games president Ted Price added later.
"It saddens me to see legislators stomping all over our First Amendment rights for their own specific interests," Price continued. "So far, there have not been conclusive studies that show that games promote violent behavior any more than movies do. "
