Like every resource survival game ever.
Seriously though, this is why I stay away from resource survival games. Almost every one devolves into a mindless, uninteresting core gameplay algorithm: walk around for hours looking for a handful of resources. Get resources. Repeat. It's not compelling for me, although I understand why some people like the building/crafting aspects of such games.
I've been following No Man's Sky as long as every else and the core gameplay mechanics have always been a huge concern for me. Yes, a billion trillion randomly generated worlds. Yes, space flight and whatnot. But what is the core gameplay?
No Man's Sky looks like it's pulled off resource survival in a much more stylish way, but at its core it seems firmly based on that paradigm. Speaking just for myself, it doesn't look fun.
Given more time and more content reveals/implementation, maybe it'll turn into that dynamic thriving space exploration experience it was hyped to be, but right now it just looks like another resource survival game.
