This was a pretty hot topic when I was in the US. And this ruling seems pretty important – games qualify for first amendment protection…
‘The U.S. Supreme Court ruled in favor of the video game industry in a 7-2 vote on Monday morning, striking down a hotly-debated California video game law that sought to place government restrictions on the sale of violent video games to minors.
The long-awaited, landmark ruling sets a precedent for the government’s role in the regulation of video game industry, and helps place the video game industry on equal ground with other forms of media in terms of government regulation.
The Court stated that the California law "violated the First Amendment."
"Video games qualify for First Amendment protection. Like protected books, plays, and movies, they communicate ideas through familiar literary devices and features distinctive to the medium," the ruling states [PDF].’
