Hardly the "majority". White males are less than 40% of the US population. I don't think we're going out on much of a limb to say that they are overrepresented in the game industry.
"Plurality" then, still the odds are on the white guy for any random task. I'm not really making a judgment, just trying to frame thoughts on the significance of the correlative factors. For non-random tasks (such as game development) we can certainly look to see why the variance of the population diverges from the variance of the general population and hypothesize to our hearts content.
