"What started out as a simple interview about a studio evolved into this: an hour-long documentary about the 18-year history of Volition, Inc. The studio provided an unprecedented amount of never-before-seen concept art and early footage of their great games, even from a couple that were canceled before their release. The video covers a lot of ground, so we divided it into four parts so that you can jump right in and learn the story behind your favorite Volition games. We recommend starting from the beginning to get a full look at not only the history of Volition, but how far the gaming industry has come in 18 short years. Let us know what you think, and thanks for watching."

I can link a couple, "Building the Bastion" has actually been really enjoyable.
