Every last thing I saw that actually came from Hello or Sony said "Wander planets, discover things, and if you want it too this fucker will pretty much go on forever. There's some online stuff, some trading, some crafting, some fighting, but really it's about exploring. If you like that you'll probably like this."
A compilation and sources of things said to be in the game by the lead designer that are either A) not in the game or B) extremely over exaggerated and unrepresentative of what's actually there. It's like someone let Peter Molyneux make a trailer for Alien Colonial Marines.
I haven't purchased No Mans Sky, nor do I plan to it's just not my type of game. But saying the devs didn't give a lot of unfulfilled promises is demonstrabley untrue.
