Video Game: Battlefield: Bad Company
Battlefield: Bad Company 2
Battlefield 3
Any Battlefield game that I can get my hands on, really. Give me a week to get a handle of the flying, and you won't see me on the ground if I can help it. Most matches where I have a decent partner/gunner I'll easily go 60/2, at my best I've earned about 200+ kills with maybe five deaths.
People need to learn how to fire a stinger. So sad.
I'm pretty good at Uncharted/Killzone from what I remember playing of them, but not enough to challenge the Devil to a round. But if he wants to play a little Wake Island anytime.. I'll put my soul and all of my future children's souls on the line.
I find I'm usually near the top of the leaderboards on most games that I play, but I'm rarely the best. I have my moments in Call of Duty, Battlefield and Uncharted, and I'd like to think I'm the best at Killzone (ha!), but I can always find someone better then me. This keeps the games interesting.

Yeah, pretty much every Killzone took quite a bit of skill to perfect/become decently good. No matter how hard I try, someones always better then me there. I remember my first time in a Killzone 2 match.. My god..
