This is the future of Nintendo, sadly. One off, disposable entertainment. This is of course what many "artists" and "entertainers" are churning out these days especially on the corporate side. And I'm afraid consumers are just going to have to sack up and get used to it for now. I think the social situation in NA and Europe has to change before people ever actually start pursuing fresh ideas and putting some basic f-ing effort into their work again, but that's a topic for a whole other discussion.
But in BotW's case this is bad for the Zelda franchise and it is bad for nintendo. Ninty is hemorrhaging fans because the Big N keeps insisting on churning out insipid, uninspired derivative drek. When fans are passionate they'll practically keep selling your product for you long after it's been finished. When fans are bored, they leave. Ninty's only saving grace is that they (allegedly) have a pile of money and a few idiotic investors to keep them in business, but if Ninty's consumer base keeps shrinking like it has they won't last. And making what few fans you have wait the better part of decades for their long anticipated game to come out only to be underwhelmed by it only turns more away.
And in that time, think about how much money nintendo spent on BotW's development. All that tech, all those salaries and paychecks, licenses, software purchases, utilities, travel costs... all the business expenses a company has to pay for. Time is money, and this is why most commercial projects don't last much more than four years generously before they're expected to hit market.
And just how well did BotW sell by comparison?
And BotW isn't even bad. It's just heinously mediocre. At least Suckward Sword has the distinction of being a steaming pile. People entertain morbid fascinations with bad things so SS can at least draw attention from some consumers who just want to see what the fuss is about. (all dozens of them - but I think SS's future sales will mostly be from kids ages 3 and up, which I'm actually sure ninty was aiming for as their long term demographic.) But BotW stands to not be remembered at all.
