Sure, many would say that No man's sky is bland, and boring with nothing to do. But from my point of view, I see it as a game of exploration and fascination with the possibility of discovering new and interesting biodiversity. A DLC with multiplayer options and a lower price might be nice.
In it's current state I wouldn't buy it, its overpriced for one thing, and the game itself is incredibly time consuming. If the gameplay issues are fixed and the price goes down I might consider it. I believe that DLC that gives you the ability to create entire planets would make the game better in itself.
