Most days I am thinking about (some days even writing) a book.
I was not a video game person until I went to graduate school. Since then, I have managed to get pulled into the wondrous world of action/adventure games, RPGs, and anything that pushes the boundaries of these ludo-audio-visual landscapes.
I really love early Hollywood musicals. There is just something delightful about people bursting into song and those dramatic stage numbers appearing out of thin air. 1930s and 40s Hollywood is terribly underrated (don't hate on the black and white film).
I prefer long-form narratives, so my bias is heavily tilted toward television and video games (RPGs, etc.).
TV: Prime Suspect, The Closer, Breaking Bad, Battlestar Galactica (reboot), Star Trek, MI-5, Burn Notice, Buffy/Angel, Friday Night Lights, The Shield, Downton Abbey, Skins, True Blood.
Video Games: Knights of the Old Republic, KOTOR 2, Dragon Age, Mass Effect, Mass Effect 2, Mass Effect 3, Bioshock (incomplete), Fable, Fable II (incomplete), Still Life, Advent Rising, Indigo Prophecy.
As for music, I can enjoy just about anything (hence the profession).
b) (re)playing mass effect 2 or 3 on the xbox;
d) musing with my colleagues.
