Correction: That part - is NOT - in the demo. It's just a demo, a brief chance to see some of how parts of the game play. At the easiest difficulty. Railroaded along to show you certain parts they want to show you. With some functionality and options removed that, from what I've seen from gameplay videos and developer interviews, are in the actual game. It's like a movie trailer or a factory tour. It's not like watching the whole movie or working in the factory.
