You may have seen reports circulating over the last few days that review copies of No Man's Sky have been very late in arriving.
(The PC release date is Friday, and advance copies of the PC version are unavailable at present.) The embargo for reviews and all other coverage generated from these review copies, which were supplied by Sony, is tomorrow at 4am UK time.
Over the weekend, Hello Games announced that the No Man's Sky servers would be reset and that a major update would be issued today that made important changes and additions to the game's structure, its balancing, and even the algorithm that generates its universe and governs the variety of planets and life you'll find.
This is clearly the version of No Man's Sky that developer Hello Games wishes us to review from, and that it considers the final release version.
I can, however, join Rami Ismail of Vlambeer in his speculation that the certification process that ensures the quality of console games, while having many benefits, is ill-suited to the way that a small indie team like Hello Games creates software - especially when the manufacture of disc copies is involved.
