I hate playing Devil's Advocate for Bethesda since it makes me feel so dirty but having so many planets that can be explored and having so much open space with nothing interesting in it is going to make the eventual discovery of something interesting.... well, interesting.until you realize they offer nothing to do
I see nothing wrong fundamentally with the concept that, without prior knowledge of a POI or a mission objective, or anything out of the ordinary, the process of discovery in a game about space exploration is going to be actually meaningful.
Besides, anything worth seeing in the game is going to be spoiled on the internet within weeks or days of release.
