I got Halo 3 which had a second disc a couple years ago, and it showed how they made it. Jesus I'm surprised they got it completed in 3 years. They got to the office at 5 to 6 in the morning and would pull all nighters. No sleep for days. And most just slept at the office so when they woke up, straight to work on Halo.
