Hard to say depending on what you want from your experience I think!
There's Breath of the Wild which is the switch game which made people actually buy the switch. Game is open world and incredible with it's exploratory and non hand-holding experience.
There's Tears of the Kingdom which is the sequel to Breath of the Wild essentially... do don't bother until BoTW is completed 😉
There is also Link's Awakening and another Zelda game which just released recently however they're top down Zelda games which makes them a VERY different but OG experience.
If you have Nintendo Online you get access to NES, SNES, 64 and Genesis games, the most well known ones anyways. There are a few games in each system usually related to Zelda in some capacity. For me Link's Awakening on the SNES was what I first experienced over 32 years ago and really excited me.
I'm dead keen however on playing Majora's Mask and another N64 Zelda title. Ocarina of Time I think...
Honestly never been into the franchise that much but Breath of the Wild has transformed the Zelda experience big time for the better!
Thx for the info my friend Im probably going to get the BOTW one pretty much well experienced with later versions… I have had the Switch for years now (have two for the kiddos) just haven’t taken the time to play around with it since I mostly play Xbox but I do miss a good Zelda game.
