UPDATE: Sony has spoken out about the No Man's Sky launch fiasco.

Worldwide Studios boss Shuhei Yoshida said he could understand why some fans were unhappy with the game, because Sean Murray and Hello Games promised features that didn't make it to the final game.

"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," he told Eurogamer.

"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."

Yoshida also said that No Man's Sky hadn't hurt the Sony brand, and that he was amazed by the game's strong sales.

Original story: No Man's Sky may have experienced a number of issues at launch, but that hasn't stopped it racking up a major PS4 sales milestone.

According to new Sony data, No Man's Sky was August's best-selling game on the PlayStation Store, and not just in Europe, but in North America, too.

Topping the North American sales chart is particularly impressive given that Madden NFL 17 was also released in August.

And as Sean Murray and the rest of the team at Hello Games works on new updates and gameplay patches, modders have once again been hard at work creating new content for the game on Steam.

New No Man's Sky mods have attempted to make the game look more like it did in the E3 trailer, while another covers planets in darkness.

One of the more useful PC mods makes it easier to find transmission towers and crashed ships.
