They have whole channels dedicated to games.
I have a video of tossgirl (google that) playing starcraft. She had quite high APM, and she used an SCV to block off an early zergling rush. That was great, lol.
On a slightly unrelated note, I'm saving up for an mp3 player. Looking for one that functions like a removable drive, has expandable storage, and doesn't suck in the output department. Any brands..?
