I don’t think that’s the right way to look at it.
Both Switch and NES have sold 62 million units:
Zelda 1 only sold 6.51 million, and Zelda 2 sold 4.38 million; but Breath of the Wild has sold 18.6 million. To me that indicates that Breath of the Wild has reached more people and is therefore more popular.
I do agree with keeping Zelda 2 around in its original form - I tend to like the original adaptations of games myself, but I am also not against having an update of the game.
Even Shakespeare has been revised and adapted.
Yeah, this is what I was originally asking for. I want an updated version of Zelda 2 (and Zelda 1 and Link to the Past) that is similar to the Link's Awakening remake. Updated graphics with some QoL refinements. I don't want them to radically change the game like FF7 Remake though.
