What do you talk about when you have Tim Willits and Fred Nilsson, lead designer and animator at id software to interview concerning Doom 3? Gameplay and engine elements, of course! It's a good read, but there's not as much on the game art side of the game. Read the Firing Squad interview here..
"Fred: The pipeline for doing cinematics is sweet - you can make a short film with the engine. I can take the level from the level designers, export it out with the geometry/polygons/textures into Maya. So I can load up that same level into Maya. If I want to animate parts of the world I can do that, can set up multiple cameras, do all the editing in Maya, and switch between cameras there."
