djdarko: I don't believe any of that for a second.
Almost every guy I've ever met has liked video games, even jocks. On the otherhand I've known 2 girl gamers, they were both chubby chicks that liked RPGs.
But hey, don't take my word for it, ask yourself what the ratio of girl to guy gamers you know in real life.
Funny. I've been a gamer since age 11, and last I looked I was female. Chubby, even, at this point in my life - does it invalidate me if I point out that I was skinny when younger and yet still gamed, on both PC and console? And not just RPGs.
I suspect that the 50% is not actually incorrect. I know an awful lot of female gamers, of all ages, but I think most of them are reluctant to admit it to guys because of the rampant stereotyping/sexism they expect for it. I can't imagine why. -.-
