Although I can't recall offhand the statistics, there is at least anecdotal evidence that in North American society, more guys who were playing video games in their childhood still keep up the activity into their 20's and 30's, although due to a lessened degree. However, I'm not sure what the story is with regard to girls, who already comprise a far slimmer portion of the gamer population in the West (compared to say Japan and South Korea). From personal observation, I know of young girls who actually used to play video games as children, but by the time they're 16, they don't care about games any more. So, in general, is there some data that indicates "disinterest" point for girl gamers hits them earlier? Or has this not been researched enough?
