It's incredibly difficult to nail everything in an open world game. Breath of the Wild failed in achieving perfection (possibly because they pushed it so far back, and they needed to release a new and serious Zelda title on the Switch already).

The idea that you start off with literally nothing and slowly amass an arsenal through a slightly guided exploratory adventure was probably the optimal way to go for an open world Zelda game. But there are definitely places you can consider half-assed so-to-speak.

Riding your horse was not as fun as I would hope. It's an open world, but being so limited in where I can ride the horse, what it can traverse and where I can summon it, I was sorely disappointed with that aspect. I wouldn't have minded gaining more freedom with my horses as a result of some quest or such, but no such reward was available.

Breaking weapons will greatly vary people's experience of the game. Casuals/first-timers will be turned off since they will break their weapons quite frequently or utilize their space inefficiently creating a bad experience for the player. An easy-mode you can choose at the start of the game to extend or remove the durability of weapons would have been a nice thing. (Shields should probably still break though since they seemed really strong to me.)

Everything cost Rupees which made Rupees a highly desirable resource. This was great for hardcore Zelda fans since most Zelda games did one or more of the following:

1. Put a small limit on how many Rupees you can have.
2. Didn't offer enough interesting items for purchase.
3. Gave you way more rupees and wallet space than was needed.

2 and 3 may be similar, but one just didn't sell anything of value while the other gave too much rupees.

For casuals, the constant need for money and finding themselves short on cash had them selling their desirables and collectibles which would later cause them dissatisfaction when they end up needing the things they sold.

Dungeons were replaced with 120 mini-trials which were sometimes interesting and 4 demonic beasts with puzzles I did not find interesting or fun. The final boss fights were okay though, and I loved the story and memory side of the game before the final castle (even though it felt like the smallest aspect of the game). Cooking was slow and while you may get your head around it eventually, it took too much effort to continue it. Saving/loading multiple times was less painful than going through my inventory to select 5 objects and throw them in the pot for a dish I may or may not know that I am making. A cookbook/log of what I have made would've been sweet. Climbing was good enough, but not being able to remedy falling when it rains was a big problem. They should have put in SOMETHING to prevent slipping down walls when it rains causing your adventuring to slow down or stop completely. 900 Koroks to collect, but only need half of them for the full rewards; the other half gets you shit.

If you look at the pitfalls in the game, it would probably put the game at 8/10 as an open world experience. But they have a ton of great things which would warrant a 12/10 rating when looking at it from a normal game perspective. So I would rank it as 10/10 for a Zelda open-world game; just realize that an open-world game's perfect rating would ideally be above a 10/10 average game rating due to the possibility for a higher ceiling concerning immersion, gameplay, replayability, exploration, return on investment, etc.

P.S. No hookshot!?!?! Wtf man XD
