This turned into a long un. Short version: These are both fair points, but ones you would expect a game heralded as the best of all time to do better.

Long version: That's a fair question, to me there's very few good examples and so many bad ones, which is why I largely avoid games described as such. For an open world setting to draw me in it must employ the aspect of exploration to reward the player with more than just gameplay resources - worldbuilding lore, storytelling or knowledge that impacts the main story.

The better parts of Fallout 4 did it well I thought, while trekking towards your destination you could come across an interesting looking building which can be explored to learn why it's full of super-irradiated ghouls or an extremely predatory deathclaw. The world is also dotted with little nuggets of environmental storytelling that have no bearing on anything but serves to add texture and context to the world, to make it seem as though it's somewhere people live - or at least lived.

I found nothing of the sort in Breath of the Wild. If you followed the most direct path to the giant glowing pillars the game invited you to use for navigating you may come across another goblin camp or fairy hiding under a rock, none of which compels you to keep exploring further save for the fact that you need a steady supply of weapons to replace the papier-mâché ones that are apparently in vogue. Other than the towers, the identical dungeon entrances and the occasional settlement the terrain is virtually featureless.

To your second point, it's absolutely true that no game can force you to care about the motivations of the protagonist, but most of them at least try. Link wakes up to a voice in his head, grabs a tablet and off he goes saving the princess. Why does any of this matter to him?

With the context of growing up playing The Legend of Zelda, you already know this - bees sting, birds fly and Link rescues Zelda. For someone new to the franchise it just seems gratuitous, and it's never expanded upon either. Link is as blank a slate at the conclusion of the story as when he woke, ready, presumably, to be put on ice till the next time Zelda needs rescuing.

Both of these criticisms can be applied fairly to any game, it's true. But Breath of the Wild and it's sequel are constantly highlighted as exemplars not just of the genre, but of the whole medium. It's fair then to expect something that's excellent in every aspect, which is absolutely not what I've found through many attempts to play them.
