it was the first zelda game I ever played when I was 7, the year it came out too funnily enough, so I have a ton of nostalgic memories of it
I love a lot of the main story moments [obtaining the pearls, the cursed sea, meeting ganon, underwater hyrule, etc.], I loved exploring and charting all the different islands, finding hidden treasures within those islands, fighting bokoblins and other enemies on the platforms and submarines, the combat was pretty fun, all the sidequests in windfall island, the graphics/artsyle of course appealed to me as a young kid, the soundtrack
and I think you get the picture, it's a high quality game that I played at the right age, even taking in all the problems with sailing around constantly
