It was launched as an early release for $59.99 and it was a very incomplete game at launch. It would be a scam to have to pay for new content. I wouldn't even call it DLC
I want the game really badly don't get me wrong. I just would like the multiplayer to be more of a co-op than what it is. I'm sure it'll become that in the near future.
I loved NMS, but it should cost $29.99 just like it used to. The PS4 version was totally $30, and it wasn't even on sale. Edit: My version was $60 though... got it on Steam when it was first released.
