when i first started playing the game it was bad , really bad but now after a lot of hours in the game over the last 6 years i can say hello games has made the game into a masterpiece.
The game is constantly changing but not in a bad way the lore doesn't change ,the basis of the game doesn't change the only thing the developer do is building and testing on proven platforms and slightly changing old ones to fit into the current state of the game.
the storyline isn't bad but short and the game has a lot of bugs which there are weekly updates for and big updates a few time a year that bring new stuff in mass
Personally i think NMS is the best relatively "unknown" game
