Should kids be allowed to buy violent video games?

In a 7-2 decision which followed no well-established ideological lines, the Supreme Court this week upheld lower courts in striking down the California law barring the sale of violent video games to minors. As always, the questions here come in two broad categories. First, was this law a good one? Second, was this law a Constitutional one? Since I do not play any of the modern video games, I am a bit out of my depth here, and so I’ll be looking for expert commentary from those of you more familiar with the games at issue in this case.
