No Man's Sky has one of the biggest universes ever created. Our own universe might even be smaller from what I hear. So why not leave your mark on one of the billions of planets in No Man's Sky? A mark that years from now people will walk by and say "Man, I wonder why anyone would waste time doing that". Then shortly after saying that they'll mark over it and ultimately make it like you were never there to begin with, making your mark on the planet and chance at immortality pointless...Matt and Andy can show you exactly how to leave your mark for a little while though.
