No man's sky is going to be an open world (universe) game where you are able to fly through space to discover other planets, wild life, minerals, and upload and name your discoveries. The universe is so vast it would take many life times to explore all of it. Everything new I hear about this game gets me more and more excited for it
Already preordered, I'm all about these open world space games. That's why I have this, Star Citizen, Elite Dangerous, and Empyrion haha
