What defines a character? It’s the kind of question we tend to ask more with novels and movies than games – but when it comes to BioShock, it’s a valid query. We’ve got two exclusive videos that dig into the evolution of character in BioShock Infinite.

We recently had an opportunity to chat with actors Troy Baker (Booker DeWitt) and Courtnee Draper (Elizabeth) about their characters and how they built the roles they’re playing. What’s most interesting: How they’ve worked together, along with Irrational Games creative director Ken Levine, to craft their evolving personas. Watch the video for all kinds of nifty insights.

And speaking of Ken Levine, we chatted with him as well. Fascinating stuff, especially how Infinite defies Levine’s previous approach to the performances in his games. Check it out.

So, whaddya think? Are you as excited as we are for Infinite? And do you agree with us when we say that Troy Baker is poised to be the next Nolan North? (Which we mean in the best way possible – Baker's got some serious vocal chops, and we’d love to hear him in even more major roles.)
