Had an N64 as a kid, but didn't really play it much. When I was 16 and got a job, the first thing I bought with my first paycheck was a Playstation 2, solely for Grand Theft Auto: San Andreas. After that, I was hooked on gaming. Currently have a Playstation 3 and a laptop I use for PC gaming. My best friend also keeps his Xbox 360 here so I'm up to date on that system as well, though it mostly gathers dust. I've owned and sold two Wii systems. Just not my thing.
My favorite games are the Uncharted series, the GTA series (or pretty much any Rockstar game), any racing game by Criterion, and Valve games of course (Half-Life 2 has been my favorite game ever for years).
I've been lucky to be able to play some of the great new games as they've been released lately, even though I'm broke as a joke. Games I've loved this year: Dead Space 2, LA Noire, Portal 2, InFamous 2, and Need For Speed: Hot Pursuit. Just bought Killzone 3 and am enjoying it way more than I thought I would.
As for non-gaming things, I'm a voracious consumer of media. I'll watch almost any movie at least once. Also love this new wave of TV. Loved Lost and Battlestar Galactica, and am obsessed with Doctor Who, which I guess makes me a giant frakking nerd but whatever. I'm an Anglophile, but I try not to be annoying about it. Love Top Gear, the new Sherlock series, Misfits, Primeval (silly but fun), Torchwood, and QI, among others.
American TV has its strengths, too. The [adult swim] line-up just keeps getting better and better. Futurama is the best thing to have ever happened. Love Archer and all of Adam Reed's other shows. Live action is also pretty great. Fringe is one of the best shows on TV right now. As a skeptic, I'm infatuated with Penn & Teller and their show Bullshit!. The Walking Dead was fantastic. And now I'm rambling. Gonna shut up now.
