Bullshit as from all reports it would take quite a bit of time to get towards the center (where the devs said in interview after interview was where all the faction system and battles would be taking place) only to find...its not there, its all been ripped out or was straight up vaporware.
At the end of the day? No Man's Sky is fraud, plain and simple. in interview after interview, some being given mere DAYS before release they touted features that did not exist and showed content that simply did not exist in game. Since the game has procedurally generated worlds? Its quite possible you get started on some shit world where it takes dozens of hours to gather the resources required to get really up and running just to find out all those features, the faction system, big space battles, planets where you have day/night cycles and weather based on its place in the system, an economy where you can be a trader or miner or make runs for various factions....they just do not exist.
A the end of the day I see NO difference between this and Aliens:Colonial Marines. In both cases you had devs showing content that didn't exist, hyped features that didn't exist, and the footage shown turned out to be bullshit. Sorry but they deserve a refund if they ask for it because at the end of the day what was shown and what they got? Couldn't be more opposite.
