Originally released at Comic Con, the latest details coming out of the Ubisoft and South Park camps is a nice little developer/creator diary for South Park: the Fractured but Whole featuring Trey Parker, Matt Stone, and the Ubisoft staff. It's a solid seven and half minutes that starts with the creative process, the backstory and transition from the previous title - Stick of Truth, and leads into detail about the development of the game itself. It's a good look behind the curtain and contains plenty of in-game footage to transmit a pretty good idea of what the final product will look and sound like.
South Park: the Fractured but Whole releases December 6th for PS4, Xbox One, and PC.
