In the outside world, I am a simple geologist... but in here, I am Valkorn, Defender of the Alliance. I have braved the Fargo Deep Mine, and defeated the Blood Fish at Jarod's Landing.
According to Jane McGonigal [http://en.wikipedia.org/wiki/Jane_McGonigal], spending just a few minutes as Valkorn, Defender of the Alliance (or whomever) can improve your attitude, your morale and your performance for the rest of the day, whether as a simple geologist, a student, a banker or a soldier.
Usually the get a life insult is in reference to a social life, partially due to the adolescent / young-adulthood phenomenon when a die-hard gamer quits gaming entirely (if temporarily) while honeymooning with a new girlfriend (or as is the case with increasing frequency, a new boyfriend). While this implies that gaming is an activity of secondary preference, it's really due to the compulsion of the honeymoon, especially if sex were previously a rare commodity.[footnote]Many of the problems of this world are due to sex being a scarce commodity to young adults.[/footnote]
As a not-so-young adult, I'm much more comfortable with my misanthropic, reclusive nature, preferring my face-to-face social life to focus around card and board games, but mostly content to interact with folks online. Left 4 Dead proves to be an excellent virtual venue in that regard. And yes, sex is awesome but it's not really that long lasting. Gaming, on the other hand, goes on as long as I like, and even meshes well with snacking and lounging.
But whether or not others approve of my lifestyle, I have one. I have a life, and it is adequately social.
