So a few misc things going off streams of the WiiU version (and don't worry, I'm sticking to thread guidelines and not spoiling a thing):
-The game has some gorgeous details and it's really cool you can see so much so far away. There's a lot of surprising touches, and some things I think will fill people with wonder and awe (can't go much further in detail than that).
-...But the game does suffer from some fairly empty large spaces in some places, there's a lot going on in some places, but other spots are rather barren.
-Frame Rate on WiiU unfortunately isn't good. It fps pretty frequently, it looks like it gets to 15-20 frames sometimes for example when facing more than five enemies at once. to be seen how it compares to Switch, but unfortunately the frame rate on WiiU is certainly noticeable. I also will clarify this isn't one place or anything, it happens kind of frequently in all areas of the game when there's more going on.
-Now I started with some of the bad stuff, but there's a lot to like here as well. The dynamicness of the world is charming, there's a lot you can toy around with, discover, and do. It really does seem to capture the simple childhood wonder of exploring a big fantasy world, which I think was the point.
-Sound design is phenomenal, from the ambient sounds, to the music, there's a LOT of detail to what's going on audio wise that adds so much to the atmosphere.
-...Unfortunately there's some really atrocious voice acting though in English. And it's a pretty wide spread thing, it unfortunately... Some of the voice acting is simply not good.
-There's interesting requirements and challenges to specific things I think is quite creative. I can't say more than that due to thread rules since it goes into side quests and such, but I thought I might mention it.
-One of the game's biggest things I think is basically everything, even the main story, is basically sidequests. You don't really need to do anything except go to Ganon, and it's already been proven on stream you can literally rush down and reach Ganon if you put your mind to it (mentioning this since they said this before release I know, but we know that for a fact now), though let's just say you probably won't get far if you go that approach. Be very fun to see how speed runners will tackle this game.
The easiest Zelda comparison is the game reminds a LOT of Majora's Mask in a number of ways, just on a much, much larger and more open scale. It's not exactly like it, but some things definitely seem inspired by it. I think the people who really will love it are those who like the idea of a big explorable and full of secrets fantasy world, and the sound design and oombat are quite something. But it's definitely not a flawless game, it has a few missteps mostly with some of the new stuff they try. Some of the world does feel like filler, the technical side leaves much to be desired in performance on WiiU at least, and the voice acting is... Hmn. But I think it's been made like this so people can sort of form their own story in the game, kind of make a big playground if you will where you can share your experiences with friends or people online or whatever since it's certain everyone's going to experience and discover different things.
All I can really say without going deeper, but hope this helps some of y'all.
about the empty space I believe they said they leave those space on purpose instead of filling as much as they can, it's the design choice they take
