That would be stupid. Yet some newscasters seemed to say it, and this columnist appears to believe it, though since she’s really just using that as a hook to argue for feeding kids, we’ll give her some slack. What it did was strike down a badly written law, in which a State tries to regulate the sale based on content of the game.
In fact, the Entertainment Software Industry already regulates sales of games to minors. Much like the Motion Picture Association, which rates movies and prohibits minors from watching certain ones, an industry association IS given the power to limit what kids can buy. Though there is not criminal or civil liability for violating the age-restrictions, studies show that it’s harder to buy a mature game than it is to get into an R rated movie. The Supreme Court did not change that. One might hope they discouraged the writing of vague laws aimed at non-problems that they couldn’t possibly affect even if enforceable, but that seems unlikely.
