To the geological formations and all, it’s just nice to explore them. For me the fun about them weren’t potential rewards, but for the purpose of exploring itself, but I get that it’s not for everyone I don’t think the world is empty though, there are plenty of nice sidequests, easter eggs and items to find, especially if you haven’t read any guides.
not really Zelda games.
