"It wasn't a great PR strategy," president of Sony Worldwide Studios Shuhei Yoshida has said of No Man's Sky.
No Man's Sky has been heavily criticised by players for not delivering on many of the things creator Sean Murray seemed to promise in years leading to release.
"I had the opportunity to play the game right before launch - and I restarted playing the game on launch day with the Day One patch - so I could see the struggle for the developers to get the game out in the state that they wanted," Yoshida told Eurogamer at TGS.
He added: "I understand some of the criticisms especially Sean Murray is getting, because he sounded like he was promising more features in the game from day one.
"It wasn't a great PR strategy, because he didn't have a PR person helping him, and in the end he is an indie developer. But he says their plan is to continue to develop No Man's Sky features and such, and I'm looking forward to continuing to play the game."
Despite this criticism, Yoshida says he is "super happy with the game actually, and I'm amazed with the sales the game has gotten".
He also disagreed with the idea that the problems with the game have harmed the PlayStation brand.
"I personally don't think so," he said.
