I bought Minecraft when it was like 10 $. Had a year and a half of great gaming until it became boring. I call that a bargain.
But, reading how ppl got bored after 15+ h of No Man's Sky is... Not good.
I guess it was a hype that made them to expect more, and they didn't get what they imagined in their minds when they bought that game.
It's not that bad, for sure, but I will wait a really juicy sale for this one. My guess, around Christmas it will be 75% off.
