I play mostly just wow, and a little Battlefield 2.
As far as not feeling like a person has accomplished anything by playing video games, i think that would depend on the individual.
The time i spend on my computer is time i have for leasure. I could be out doing other things, but none of them are any more or less productive. I would rather be on my computer interacting with other people than sitting in front of the tv watching nothing in particular by my self. I have the rest of my time to spend with personal friends and family.
