practically this. i didn't care enough about the story to continue into portal but i appreciate the voice, it'll be a nice bit of trivia knowing where its from when i watch this with whichever chica has a couple of hours to spare.. should "whichever chica" recognize the voice and make mention of it, we shall be wed before the morrow.
Good move, I showed the trailer to my wife and she was like 'THAT'S GLADOS!'.
But then again, she also posts on GAF.
