Not to defend Hello Games but there's a slight air of consumer infantilization in that thread : Anyone applying a bit of skepticism did see through it years ago, regardless of devs going bonkers with the marketing. Would be nice if all games were advertised truthfully at every moment but meanwhile consumers will continue to have to do due diligence.
Sean Murray lied about his game in every other interview or live demo he was part of, not many devs actually do that, AAA or otherwise.
Features being removed or scaled back? Yeah. Devs pretending there wasn't scaling back or things weren't removed, even after release? Doesn't happen. Ubisoft came forward with Rainbow Six Siege not having single player before release, pulling a Sean Murray would mean they pretend there was no expectation of single player and don't respond to questions.
This gen has a lot of bitching, justified and unjustified, sometimes the bitching is about particle effects or smoke, sometimes its about a woman character that has huge tits. No Man's Sky is a clear example of a developer lying about their game.
I was incredibly skeptical of No Man's Sky, and the end product is worse than I thought it would be.
