The ESRB Don't Get No Respect
Via the ffwd linklog, a story on the Hollywood Reporter site discussing the public image of the ESRB, from "pain in the butt" on the developer's side to lax child perverter on the lawmaker's side. From the article: "The issue Greenberg describes is one involving dollars and cents: Almost every single retail chain chooses not to sell 'AO' rated games, period. In just the same way that many movie theaters will not show films branded with an 'NC-17' rating, the 'AO' severely limits a game's distribution, to put it mildly."
I don't know what world you live in, but in this world countries have banned several video games, and that fact was used as a selling point here in America. The only thing we really censor is nudity, we just try to control the amount of violence that a child observes here in America.
Example, Carmageddon was banned in Australia I believe, as well as Postal 2 and more that I can't remember off hand.
Also, it may be the parent's job to do so, but you have to admit that children can be pretty convincing/conniving if they want a game that is "Adult" enough. And, the industry is pretty guilty of trying to sell on that type of appeal, whether they want to admit it or not.
