Horrible launches can be corrected with dedication and perseverance from the game studio. No Mans Sky is the perfect example of a failed launch turning into a brilliant and well-supported game. The real question is does NQ have that kind of resolve? Currently, all signs point to no.
Some have said that NQ's problem is that it is a small studio. Well, Hello Games is also a small studio and they managed what everyone thought was impossible after their launch.
