With all the categorization of people into different classifications, we seem to miss one key thing: the whole point of video games is to have fun. So when casual gamers come by, like girls getting into our tree house, we tend to react badly due to our fear of being marginalized, not to mention the fear of cooties. If I've learned anything in thinking on this subject, other than the fact that abrasive pads aren't fun to bathe with, it's that the hardcore vs. casual gamer debate is a bit silly because in the end, because the point of all of this is just to play. Have fun. And instead of trying to judge someone for the games they play, try to frag them instead.
