I like this quote from the Hacker News thread about the awesome TOTK sales:
nintendo's playbook: bet on withered technologies.
which means their focus is only on gameplay mechanics, story and art direction. not focusing on bugs that are well not known cz of using something too new, expensive etc.
not fancy graphics, or other modern fancy things - that don't really add anything to the game.
wish the software industry would learn to bet on old technologies and develop novel experiences on those.
not the current - move to the latest framework, hardware etc. while presenting shit.
There's plenty of other good discussion in here too.
