I'm not always a huge fan of developer videos, simply because they're often overly long or heavily scripted and edited. They often feel forced, and lose any organic flow that you might find in a spotaneous chat. The new Fly on the Wall miniseries from ArtCraft Entertainment does away with this, and films the deverlopment team as they chat about a specific item. It's fascinating to listen to and shows how they're going about making Crowfall; warts and all.
