I'm a pretty big fan of nonfiction. How-to manuals, encyclopedias, and textbooks. I also like graphic novels. I used to be a big anime fan in high school, but I've fallen out of habit of watching it. Recently I've been buying up DVDs though to support the industry I pirated from so much in the past.
I like video games, especially PC games. I'd say though that I like discussing them more than actually playing them.
