I played other games by FD including planet coasters and Jurrasic one, and I refuse to believe that big studio like that cant pull NMS like planetary experience in ED. Engine can do it, they have talented programmers more than capable to do it, the only reason I can think of why we still dont have atmospheric worlds to land on is because ED is not money maker and its simply not profitable to put work force to make content like this possible at this time. Its a business decision, not tech limitations imo.
I doubt that it isn't a money maker otherwise they wouldn't do beyond for free.
I wish the community would make up their mind. There are some that are saying ED is a cash cow and there are others like you saying ED is a dog. It can't be both.
I don't think it's either, it is somewhere in the middle.
Personally I think they reason why they don't have atmospheric planets is because they want them to be as realistic as possible and that is going to take time.
According to FDev ED is doing better then ever and there are more people playing the game then at anytime in it's history. Right now would be the perfect time to bring out a new paid for expansion. I see atmospherics as that expansion. May not be earthlikes or planets with complex life though. That will take longer.
