Though the median age of video gamers has increased dramatically over the past decade, a recent report from the NPD Group shows that youngsters still possess a great deal of market dominance -- according to the study, households with children ages 12 and under constitute 45 percent of the gaming industry's total sales. Considering these tweens only make up 17 percent of the U.S. population, that's a fairly large chunk of selling power.

Still, it's tough to completely trust these numbers -- as we all know, 13-year-olds are vile, fraudulent creatures who are quick to shave a few years off their age in the pursuit of pure vanity. Just be yourself, 13-year-olds. You've got plenty of good years ahead of you.
