In the above video, little Riley goes off on the way toys are marketed to kids: blue and superheroes for boys, while girls get pink and princesses.
While she's specifically talking about toys (she is in a toy store), I agree with so much of what she says. And so much of what she says holds true for how video games and video game hardware is sold to each sex. Game companies pander pink game hardware and pink games.
Back in 2006, I got a pink DS Lite. I wrote about it here in this post with a tongue-in-cheek title. In Japan, pink isn't always a feminine colour. Cherry blossoms, which are pink, are macho -- hence why Japanese gangsters get them tattooed on their bodies.
Riley's right, because sometimes boys want pink things. Sometimes girls want blue things. There's nothing wrong with that.
