New Story Content
One of the main additions brought to the game is new story content for the Atlas story branch, hence why the update is called Atlas Rises. The developers have said that this will total 30 hours overall, which is more than the length of a lot of single player games.
The story may not be the most important aspect in an exploration game like No Man’s Sky, but the fact that the developers have added to it in an update that released around one year after the game came out is a good thing. For some players, an enhanced story gives them a sense of purpose while playing through the game.
