Lets keep in mind too that the ESRB and their ratings are not definative, but more like suggestions. Overall, its upto the PARENTS to decide if the games are appropriate, NOT the government. One of the big complaints is Californias view that if you are under 18, you can't make decisions for yourselves, and the government should be there to back up parental values. Not all parents have the same set of values however.
I am glad to see that 9 States and our protectorate are on-board, and are fighting this. Its not a matter of "selling games to kids is bad", but a matter of opening up the definition of "free speech". If this were to happen, who's to say the internet wouldnt be considered freedom of speech, and have our thoughts censored?
