Maybe you already read somewhere that Arnold (now the Gouvernour of California) recently signed a bill that restricts sales of violent video games to persons above 18 years of age, and the gaming industry out there doesn't really like that. So what do they do? They sue Mr. Schwarzenegger and as some examples from the past show, thay had success which such behaviour in the past.

You know, we have that kind of censor-ship here in germany for some time now and I dunno why the game industry over there in California (maybe too much sun burned some important parts) has problems with those restrictions. There just are games that shouldn't be sold to minors (just think of recent games like F.E.A.R. or Quake IV) and there also are parents that don't care. So if parents fail and stores don't care about the age of the buyers, it's the state's duty to do something. But as said everywhere, you now can see that the gaming industry clearly is only about money, otherwise they wouldn't act that way. They may come up with things like "this is pure censorship" or "it's the parent's duty to see what their kids do", but at some point one just has to stop those industrial madmans from selling anything to anyone. If you're a bit into history, you'll quickly realize that such behaviour will someday end up in a new age of decadence.
