He keeps lying, but aww he's so "humble" http://thisgengaming.com/2016/08/15/sean-murray-says-he-was-perhaps-naive-in-saying-no-mans-sky-wont-have-paid-dlc/
One thing you won’t see however, is the studio exploiting that with micro-transactions. Murray is adamant on this point. “We do want to add a ton of features, like we’ve just discussed: Freighters, bases, these type of things. But we want to do it for free. You’ve paid for the game, so you should get this stuff without paying even more money. So no, there will be no paid DLC, just patches.“
Yes, that’s a quote directly from Sean Murray; “there will be no paid DLC, just patches.”
Well in an interview with the Daily Star Online Murray has now changed positions. Murray told the Daily Star Online that he was “perhaps naive” for suggesting No Man’s Sky will only have free updates.
“When pushed on whether the game will always remain free, Murray couldn’t categorically rule out paid for DLC further down the line, explaining that it could happen if “Maybe in the future there’s some reason why we just couldn’t possibly afford to do a certain feature without charging for it”.
