Not a lot to say here, other than, “Good job affirming the obvious, Justices.” The problems with California’s violent video game law were legion, and I think you’d have to bury your head in the sand to think the Court would ever approve of the law. Both sides’ reactions have been typical; the industry is positive, the senator is negative. Without hearing statements from either side, I could probably quote them verbatim.
For all the standardness of the story, though, this is a big step. They shouldn’t have needed to, but the Supreme Court has affirmed that video games are as valid a form of First-Amendment-protected speech as books, movies, or plays. If you’re going to regulate games, you must simultaneously regulate the rest, and good luck with that.
