Hehe … they already made so unbelievable much money that they will not invest a single $ into further development of NMS. Instead they either are happy that they dont have to work a single day for the rest of their lives - or they do plan on a new game.
It was about 212.000 simultanious players on day one just on steam.
So if you wanna get rich then create a new game mechanic and hype the **** out of it. Everybody will be buying it out of curiosity.
This might still works for the next 2, 3 games of this kind
