A theory on my discomforts in life and dormitories

At home, I never had a problem with spending a Friday night in my house, gaming. Sometimes gaming is just the right thing to do, ya know? Gamers game, it's what we do. However, now that I am in college, every night I spend in my room playing WoW, Final Fantasy or anything else along those lines feels like a night wasted, no matter how normal it is for me. And it's not a matter of me not enjoying gaming as much as I used to; FFXII has brought fantastic feelings to me that remind me of some of the best games I've ever played. And it's certainly not that I enjoy being out of my room more; I was just out drinking some with some attractive ladies and cool dudes, and I really wasn't having that much fun. So what is it?

My theory is that dorm life is what causes this feeling of inadequacy in myself. When I'm at home, I see people in school, but when I'm at home all I see is my parents or brothers. Or I see my friends, who for the most part have a similar philosophy on having fun as I do. Here at school, on the other hand, I can hear people out, being drunk as hell and having a good time doing it, at least three nights a week, usually for about six hours straight. And they have so much fun doing it... even though I really don't enjoy it, I still envy them. And closing the door really isn't an option... it's somewhat a taboo here, to close the door while you're in your room (unless you're sleeping or studying). My roommate, and most other people I enjoy the company of here, would find it weird and not appreciate it. So I'm regularly subjected to the message "socializing + drunk = fun," which leads me to feel like a lame person for not doing so every weekend night.

This is just a theory, and certainly isn't set in stone. It was triggered in something Kari said to me, actually, about why she isn't at Southern anymore. But, it's something I'm thinking about, and I'm wondering what to do about it.
