I don't think I'll ever quite, but I could see myself cutting down. Like you, I don't watch much TV or many movies. However I do find video games relaxing, and you know what. After a long day of work, or school, or even just a day spending time with friends, I really like playing my favorite RPG for an hour before bed.
I would much rather hang out with friends until the wee hours of the morning, but people are busy, and schedules conflict.
One thing I do want to change in the future though is I want to read more books. I like playing my DS at work, and nothing beats a good ol Pokemon fight, or a classic JRPG remake, but I do feel a bit odd when I cram in 2-3 hours of game time at work (I work at a job which involves a lot of waiting around). I just want to fill that void with books a bit, but damn that book store...how do I know if I'll like a book, or if the book is the type of book I'll like? I wish I could do more then just take the suggestions of the people who work there. I feel like a mom in a video game store when I'm at the book store. So for now I'll stick with scoring books off friends.
