Honestly, I think the original. I know its inferior to most of the other games in most ways, but I’ve found a lot of the modern Zelda games feel pretty shallow and formulaec. Not to say they’re bad, but none of them really feel like they stand out to me either - they’re just good games. The original on the other hand, feels very different from a lot of the games since then. The world is kept a lot more foreign and hostile both in terms of aggressive enemies and in terms of tutorialization. Its makes the exploration so much more rewarding, and when you do find a new item, that much more special.
