Although you can’t call a first party title technically but, Sony is going to be treating at such regardless.
No Man’s Sky has made a huge name for itself because of the brilliant tech behind the game. It is simple, beautiful, and is promising an endless sandbox for players to dip in. This seemingly brilliant creation from Hello Games is a timed PlayStation 4 exclusive, and Sony plans on taking advantage of that window to the max.
Talking with MCV, Sony UK Managing Director Fergal Gara said,
"No Man's Sky has been treated as if it was from one of our internal studios. We have been working very closely with the developers and bringing it into our release program as if we had made it.
We are not going to treat it any differently and we are going to put the full weight of PlayStation behind it. If it all comes together as well as expected, it will be treated like a first-party release; it is not a self-published small indie title on the platform."
After the PS4, No Man’s Sky will make its way to the PC. There is no word however whether it will ever be launched on the Xbox One. As such we are fair to assume that this game should be considered a PlayStation Exclusive.
