I think that, considering that the majority of the gamer populace is 20s-30s, there are a whole lot of more "normal" guys out there that skew the scales away from nerd stereotypes. The kind of guys who buy Madden, Halo, and Call of Duty (I fall into the latter two category, anyway). People like your Wal-mart buddies probably aren't the majority, but there are plenty of 'em.
