For the last couple of days Ken Levine, Creative Director at Irrational Games, has been camped out in our BioShock forum responding to your feedback about the recently released BioShock video

This morning he started another thread with his response to the most common questions, as well as a few points he'd like to clarify

All the voice acting came from an impromptu short session we did before the demo. The Little Sister will have a full suite of dialog, as will all the AIs in the game. Our goal is to have substantially more character dialog per character than even other IG games.

Regarding my voice: I'm not actually a serial killer, but I will be playing an evil clown vending machine in the game. I know you hope I'm kidding, but I'm not. I've also decided to use Jade Raymond from Assassin's Creed to do all our future PR work because she's way hotter than me.
