So much hostility... Let me straighten out this whole CG confusion. There's basically 2 types. The very nicely looking, long, drawn out method used in the movies, where every bit of detail is hand crafted frame by frame, and the technique where the game engine renders the scene. The latter takes very little time to do. At the least, they can use premade animations and camera tricks to put together a scene very quickly, which I can live with. At most, they can use motion capture to create new animation, and that doesn't take long either.
