Video: BioShock developer diary

GameTrailers has posted a developer diary video from Irrational Games, makers of BioShock. Of course, if you're going to talk about BioShock, you might as well talk about the Big Daddy. It seems that he (it?) has wormed his way into every bit of BioShock promotional material out there, and this video is no different. Specifically, the video deals with the relationship between the Big Daddy character and the Little Sister. The two are always together and will work together when confronting threats. It's really an interesting look at how the pair interacts with each other. It's almost heartwarming to see the Big Daddy affectionately pat the Little Sister on the head, though the feeling is somewhat sullied knowing that he most likely drilled someone into a wall only moments before. Watch the video and tell us what you think.
