Some gamers felt that the images, video,and text on the Steam Store Page for the game were misleading. The ASA heard 23 complaints against the game claiming that the screenshots and videos depicted advanced animal behaviour, large firefights, and ship-flying behaviour that didn’t end up in the launch version.
Some alleged that the screenshots misrepresented the graphics of the game and complained that the lack of loading screens and factions to fight over certain territory was misleading.
The ASA talked to Valve and Hello Games, but most of the investigation focused on Hello Games.
ASA ruled there was no false advertising because the developers assert in the advertising that No Man’s Sky was a procedurally generated game and the play experience will vary.
"Differences in the systems generated by the game and power of player’s computers would also affect the quality of the graphics in the game and the ASA says it believes most consumers would understand that. The summary description of the game made clear that it was procedurally generated, that the game universe was essentially infinite, and that the core premise was exploration. “As such, we considered consumers would understand the images and videos to be representative of the type of content they would encounter during gameplay, but would not generally expect to see those specific creatures, landscapes, battles and structures.”
