As a girl, I have to say that I wouldnt ever consider buying any "girl games" even if I was 8 years old. That I would think is becuse I got my gaming interest from my dad from the beginning, we played Tomb Raider and Midtown Madness. So I do prefer games that are either unisex or the ones labeled "boy games".
However, some of the games showed in the article, makes me sick. I really think they could really influence the younger girls who buy these games, or even worse, parents buying their young girls these games, to think that they have to be stereotypes. To think that this is how they should be, how they should look, how they should act. Which is horrible.
But some girls indeed like ponies and make-up and pink, personally I prefer snakes and Fallout 3 and gunmetal gray, but these girls do exist. And ofcourse they can like these games, its their choice and taste, but I personally just think the games are really silly, and a pathetic attempt for the companies to make money. I dont like the games, but thats my opinion.
