> no real relationship other than making money and appeasing fans

That's a very cynical and dare I say Hackernews take. You could also, less cynically, see them as unique pieces of art that have managed to carve a space in a field where, by necessity, a lot of money is needed to create it (AAA games).

Tears of the Kingdom is art. It's a beautiful, simple fairytale told through the medium of a huge open world game and there's something unique in being able to embody that story for so many hours. I haven't played any other Zelda games from the past ~20 years but if they're similarly artful (and by all accounts they are) we don't need to be cynical towards their simplicity or the fact that they're variations on a theme. Pretty much all human art (and business) is, after all.
