Who said we couldn't change the Ghosts's voice in the first place? Now give me Samuel Eff'ing L Jackason Or better yet - GlaDOS

We don't want dinklage back anyways, I feel more confident with a professional voice actor than a regular actor, although games like until dawn have shown how good actors can be in games.

There are a couple factors with that. Firstly, he's not a voice actor. He's talented, but in other areas of acting. Secondly, they mentioned that he's not anywhere near as available as they needed him to be to get the lines done properly. So they needed to go with someone more open. And let's be honest, his voice acting was mediocre at best. I love him as an actor, but even the best of the best can -blam!- up sometimes.
