I still kind of have my doubts about this title. I have been playing several free roaming/sand box games such as Subnautica, and after a while I just became bored with it despite how much it offers.
Even if No Man's Sky turns out well it may not be my game.

For the same reason I don't play Elite Dangerous either. Lots of freedom for players and you can decide your own type of career, but I just can not focus myself on it. (mind you, I am going through a depression right now, that also effects me)
