Portal 2 comes with a feature to turn on subtitles (closed captioning) whilst playing the game. I really like the font; but I have absolutely no idea what it is.

I'm pretty sure the same font is used on all platforms of the game, including PC.

Any idea what's the font?

Edit: The preview I showed is from a full-screen HD 1080p video on YouTube. If the font's a bit too blurry, here's the same screenshot of the video but without full screen. The font is smaller, but it's clearer. http://i55.tinypic.com/236t7b.png
