what is wrong with rating games (or anything else for that matter)? surely we can all agree that there are plenty of games/movies ill suited for children.
There is a difference between an advisory ratings board and one that has the power to effectively legislate their vision of morality by refusing to rate certain things.
This. As SpardaSon said, our MPAA (for movies) and ESRB (for games) are private associations whose decisions carry no legal weight at all; they're simply meant as guidelines for consumers who are concerned about media content. There are adults-only classifications for both movies (NC-17) and games (AO), and while certain stores may choose not to stock titles with those ratings, they can still be handled within the system. (Incidentally, the reason why no game has ever been released as "adults only" is because Wal-Mart refuses to stock titles with that rating, and they happen to be the country's biggest games retailer.) More importantly, you're perfectly free to sell your product on your own without submitting it for a rating...you may not get it in any retail stores, but there's nothing preventing you from doing so, which is how it should be.
At the end of the day, I just don't see how it's in any government's purview to rate and restrict media content, especially when that extends to flat-out prohibiting the sale of certain pieces of entertainment in the country.
