I disagree with referring to them as "sports", but to be honest... if you think about any other activity that has as many active, passionate participants as gaming, that's also widely accessible to anyone (to be honest, only sports come to mind), then when you draw the comparison it doesn't seem as crazy. Many sports have millions upon millions of dollars invested in them without us even batting an eyelash.

EDIT: Also, loving the new set. :lol
