Zelda didn't flop? Lmao.
But I do agree that without indie devs being added to Switch platform, it would be completely dead. Nintendo haven't really made any new IP for a very, very long time now. They release a new Mario/Zelda game every what 2-3 years now or something?
And yeah, the new Mario/Zelda games have interesting new things in them (and are super fun) but are still relatively cookie-cutter.
I've started collecting "retro" games from my childhood now and been buying GB/GBC/PS1/DS/PSP etc games and it's crazy to go back because I really am starting to notice how many new franchises and interesting gameplay elements older games had.
Even if those franchises didn't succeed/get sequels it still added fun/value and variety to the platform. But it seems like the game industry is playing it safe now, every x time we get a new Mario/Zelda/Halo/CoD/etc. Playing older games now it's just so much fun to see "oh this one they wanted to do x but with this weird y thing" even if y was annoying & it didn't work out, it still makes for an interesting/different game. Same thing with Nintendo, they're playing it safe now after the era of "what if we based our console around motion control" spawning many a Wii sports meme. Now it's "we so smart, our console is handheld and TV console"; bruh the PSP go did that (I suppose the detachable joycons kiiind of count?)
Sure there are indie games in between but I've also noticed that indie games...aren't as good as they used to be? Like the golden indie age was maybe 2010-2016 or so? There have been a few hits since then, but I really feel like indie games have become formulaic especially the "make something crazy & quirky by design" formula, as opposed to previous indie hits that turned out crazy & quirky, but weren't planned to be; it's just because the developers' personalities were that way and it really shows with how polished and loved some of the older indie games are.
I guess the slice of indie pie for people that start a game with "I'm going to make this game & sell it & it will be an indie hit" has grown larger compared to the "I'm gonna make this rad game that I've wanted to make since I was a kid and I'm making it for my friends & I if nobody else" which has become a smaller slice.
