South Carolina urging parents to examine video game ratings

I went to the official ESRB website and stumbled across this press release. . . South Carolina Attorney General, Henry McMaster, launched a campaign encouraging parents to use the video game ratings as an aid for making purchasing decisions for their children. I agree that parents should know about the ratings and use them accordingly, however I believe that most parents already understand the meaning of the ratings because they are pretty self explanatory, (i.e. E for Everyone, M for Mature,etc). I feel that the clarity within the rating leaves no need for a PSA and is a waste of time. In general, I feel that there are much more important issues requiring PSAs for parents aside from being able to translate the game ratings on video games.
