Hard for me to say when you remove video games from the equation. I've been playing for as long as I can remember (there was already an Atari 2600 in the house when I was born), and it's really my only consistent hobby.

But I guess my other one is writing. I own a few blogs, I do freelance writing on occasion, and I've written articles (on writing and argumentation) that have been used in school syllabuses here in the U.S. and [I think] Australia. I call that my hobby, but it's really my "career," even though I've been lying low for a couple years after graduating.

I admit it: I'm not career-oriented. Job market here sucks, too. >.> So I waste my time doing smaller things rather than getting an actual writing job.
