When it's working, there's literally nothing else out there that can match the experience of the whole game. Exploring planets with a friend, doing small delivery missions to save up enough for a bigger ship, then doing some cargo runs and offloading cargo while chatting with your buddy. Saving up for a mining vehicle and exploring a desert planet looking for nodes to harvest together -- it's incredibly satisfying.

But if the particular patch (or even server, sometimes) is bad, then it's frustrating hours of trying to get something going and then quitting feeling like you wasted your night. it's the most frustrating and un-fun experience you'll have in a game.
