When I was younger, we had 2 TVs (one for older brother, one for living room) so i was generally accustomed to not playing games in my bedroom until just about 10 years ago when I pulled out a small once presumed dead TV from our basement. I love having the close proximity to my games, and now in a dorm (although my setup is very bedroomish) I feel the exact same way.
I collect games, and prefer to display my collection in my bedroom. Plus, I generally have extended periods of gaming (whole days dedicated to particular RPGs) and doing that in high traffic areas isn't the best idea.
