Hello Games founder Sean Murray took to Twitter recently to explain the PC release date for No Man's Sky is slightly different than the release date for the PlayStation 4. How different? A couple of days different. It will be releasing on August 12th instead of August 9th.
PC [No Man's Sky] release will now be global and will be August 12th worldwide. It's so important we get it right and make the best version we can, [...] We [apologize] for the extra days wait this means for North America. Steam page will updated to reflect this asap
There are reasons we have to be tight lipped at times. I'm sorry for the confusion caused. We think a global release is best for everyone on PC. Retail forces us to be staggered on PS4.
The delay isn't that bad, especially considering that the previous delay for No Man's Sky was from June to August, which was a heck of a lot longer than the minor delay they encountered here, where it was only pushed back by a few days.
Sean Murray doesn't explain what the delay was for, but only keeps it brief and general about making the game better.
Presumably there are a few things they plan on fixing ahead of its official release but we don't get any details on that. Plenty of No Man's Sky gameplay footage has been leaked ahead of the game's release from the PlayStation 4 version, and so far it appears to be fine. In fact, more than four hours have already been uploaded online and there has been nary an issue that I've seen.
Of course, No Man's Sky is a huge game and it spans the likes of a quintillion planets across a massive universe of nearly countless solar systems. I have no idea how they've ensured that all of the planets are proper and that none of them are glitched, but I'm sure with only a three day difference between the PS4 release and the PC release, they aren't messing with the core mechanics too much and will likely instead be focused on optimizations for the most part.
Then again, it could be something else entirely, perhaps a graphics issue? Maybe it's a localization issue? It could be a debugging issue, a loading issue or a minor network issue. Whatever caused the delay was only big enough to push the game back by a few days on PC, which isn't too bad.
Some of the comments on the IGN article were a little bit peeved at the delay, but most recognized that having to wait three days was not that bad compared to the fact that the delay cold have been far worse and No Man's Sky could have ended up being pushed back by a month or two for PC.
Regardless of the delay, right during the midway point of August PC gamers will be able to get their hands on No Man's Sky and enjoy it alongside PlayStation 4 owners. The only question is now is whether or not the game will live up to the hype?
