Possibly because No Man's Sky is likely to tank. Nothing I've seen of it thus far has me convinced that it will be anything other than an elaborate tech demo.
Spore 2, here we come.
I really don't want to agree, because I really want to see No Man Sky do well. But alas I have this same feeling for the game. I hope they are just bad at explaining the game and hope there is more than just exploration in the game.
I don't blame the devs either, I just think they're in way over their heads. They were set to make a $20 indie game and suddenly the entire world's eyes are on them as they're pushed to make a AAA game instead.
