Good point. But he does make the notion that games usually have as good writing as the consumers who buy them, thus the stigma of being immature themselves.
And AO is a very big "No-no" in games in the US, since it usually means, compared to movies, that it contains explicit sex or direct pornography. And since a nipple-slip in can be considered as "AO" in games, well go figure. And as Xard said, the biggest supermarket chains refuses to sell AO-games, leaving the market self-censored.
