There are many benefits to recording dialogue audio for a game. It's great fun to watch your characters come to life, it's thrilling to hear somebody else interpret lines that you have written, and it really enhances the atmosphere and the sensory impression of the game.
There's also a problem with it though: You have to work with actors. And actors are scary.
This is Chris Zito as filmed by Marc Swint, another of our actors who kindly volunteered to direct Chris in the recording of a very large character. One of the things we've learned while developing TNM is that it's always good to have somebody direct the actors - even if the director doesn't have a lot of directing experience, it really help to have a second opinion in the room during the recording.
To get a bit of an idea of exactly how massive the voice acting undertaking for TNM has been, here's some stats:
Deus Ex's conversation audio files take up a total of 182 MB. TNM's conversation audio files take up a total of 298 MB so far. That's well over TEN HOURS of voice acting, people!
Another rather scary factoid: The TNM installation is now 1.8gb. Prepare your hard drives for the January release!
