It is pathetic. But its actually quite normal. There's segmentation in the interests of the two sexes. In Japan, its called shounen (action+fighting+leveling up+fighting powahh!!!!!) and shoujo (romance + love + magical girl transformations + I dunno it that well).
Gaming has leaned more and more towards shounen. We have rpgs, leveling up, strategy, fps, action, sports, fighting... all of these genres fit under Shounen. Hence it is normal to see a large population of males in the gaming industry.
Actually, Shounen is still only a fraction of males, hits hardest in the teens, and dies down when you turn twenty-two and enter the work force (on average). The same for shoujo and females. The majority of people have very little shounen or shoujo in them.
Nintendo's strategy for success is to blissfully ignore the extremes and to create games that cater to neither shoujo nor shounen, but rather something more universal. Their biggest hits are like that. What is it? Practicality? Pure Distilled Fun? Real life done right?
Who knows. What I can tell you is that because of the success of Nintendo in the older generation and in females, the Next-Generation after this will be very strange. And as long as game developers still rely on shounen as their selling point, Nintendo will continue to dominate software sales.
