Dude, everything you wrote here is wrong. It got the majority of its bad reviews at launch, then after that when it would see a spike of new players the positive reviews would dwarf the negative ones. They also pretty much fulfilled all the initial promises by like major update 2 or 3 or something, right now we are in update 10, they keep adding new neat stuff. Lastly, you can't call something that sold over 6 million copies just on pc dead on arrival.
Yes I can, because the second it arrived everyone hated it. No Man's Sky is a byword for lies and failure in the games industry. That they managed to finally, years after launch get it to a playable state is sad. Hello Games doesn't deserve respect for the hard work they put in to fix their broken product, they deserve scorn for selling a broken product in the first place.
No Man's Sky is not a success/underdog story, its a campfire story told to young developers to scare them into not lying and laughing it off as a quirky developer. To quote from No Man's Sky's own Wikipedia page:
"The video game industry has used
No Man's Sky as an example of missteps to avoid in marketing "
Also the numbers at launch sold don't mean anything if Steam had to change their own refund policy to allow customers to get their money back.
