Things have been taken out of the game prior of release, and there were different builds showing in the trailers, all that's true, we can all be obset about it yes, but really... do we ever make such a discussion for other major game titles where this constantly happens almost in total silence? No, I have never heard this kind of negative hype like the one for NMS.
Aliens: Colonial Marines got the same treatment, so I return the question: If ACM got bashed for its misleading marketing, why should No Man's Sky get a pass?
I shall leave this here as well, a good overview of what happened prior and after the release:
EDIT: Something I was not aware of until I just checked: the game is still, two years after release, sold at a full price of 55€.
