&gt; <i>Clearly there would be a significant IQ difference between the average sports fan and the an average D&amp;D player.</i><p>Really?  What do you base that claim on?  The fact that lots of &quot;geeky&quot; people play D&amp;D doesn&#x27;t mean that the average person playing D&amp;D is actually smarter than the average sports fan.  In college I knew some smart people who played D&amp;D, but I knew some dumb people who played it, too.
