I dunno, I'm fairly introverted as a person and after a long week working, social obligations, hanging out with gf and friends (luckily they also like gaming), sometimes there's nothing better than spending an afternoon or weeknight just playing games for hours straight. I don't understand the whole "you have to be constantly productive" or "constantly do things to better yourself". Sometimes you need that mental break. And it helps me to appreciate the games I do play a bit more, I think.
