feels just like a second half to me
replayed BOTW before TOTK, all i had to get used to was the hand abilities switching around
OoT removed your ability to use Deku Sticks, your Slingshot, your Boomerang and just kind of left you with your Sword, Shield and Bombs, TOTK got rid of essentially the same things and threw you into a similar landscape with a few changes but more to explore.
I think a lot of people will always rate BOTW higher because Hyrule was new to them, going into TOTK, they don't have a vastly new Hyrule to explore despite the ongoings being different, mix that with people being upset that not every NPC knows exactly who you are and that not everything done in a sidequest is the direct result of Link and people will feel different about it.
It's not super often that fans that started with the 3d titles have gotten to deal with the same Link, and it's even more unusual we got to do so in the exact same Hyrule with the same cast (Roughly) so a lot of people were expecting more direct explanations and for it to be a more direct follow-up than they actually got.
I think between stuff like Tarrey Town being something they didn't get direct credit for, and Zelda being the one to get the house and they start feeling "robbed" of that glory despite it making sense.
Link starts his quest, hits up the respective important spots, and in doing those definitely hits the 40 (36, not counting the Plateau shrines) or 24 Shrines (20, not counting the Plateau shrines) before wrapping up Calamity Ganon.
It's been around 6 or so years in universe, and that's plenty of time for things to get wrapped up between the games, but that's unsatisfying for some people because they feel more disconnected from the game because the things they "accomplished" no longer mean anything because the game isn't directly referencing or addressing them.
People are going to be talking about more than just the gameplay of the games, and for the people who didn't like receiving the same info from the sages, it's gonna bog them down.
TOTK's Sage abilities are infinitely more balanced than BOTW's because they're items meant to be used to progress rather than rewards for completing a dungeon, but they feel worse to a lot of people because they have to position differently to actually use them.
Tulin is a Deku leaf/Gust Bellows, Sidon is a Sword Beam/Water Shield that resets burning/heat, Yunobo is a Bombchu/Firerod that also functions as a Cannon, and Riju is a Bomb/Shock Arrow.
also Mineru is literally Dark Cloud 2's Ridepod/Steve
BOTW's dungeon rewards are a Recharging Fairy, Nayru's Love, Roc's Cape, and the Quake Medallion, but all of these are things you can do that make you "hugely" more powerful.
Miphas Grace "feels" better for people because it's an extra life, Sidon's doesn't feel as good because it defends against damage or allows for more (but also has cohesion with Zora Weapons) but you have to run to him to activate it.
Daruk's Protection "feels" better than Yunobo because you can activate an I-Frame whenever you want and perfect parry whatever you want without risk, it's instant and you don't have to be anywhere or deal with positioning to use it.
Revali's Gale "feels" better than Tulin because BOTW doesn't have as many free verticality tools as TOTK, Tulin will let you boost through the air, but it doesn't feel as useful because you have Zonaitems to help you with that too.
Urbosa's Fury feels stronger than Riju's because it'll skullcap and stun everything around you in an instant and you don't have to aim to use it, it's an instant "I'm overwhelmed, and want the fight to end." button.
Using items isn't as simple as just having Ice Arrows, Fire Arrows, Shock and Bomb Arrows, you have to have normal arrows and the right materials, and the menu steps required to do it don't feel as smooth.
There are a LOT of neat things that TOTK does, but because it also offers so much freedom, there's much more people feel they don't have to engage in because they made a solution a long time ago, people rush the Instant-Build ability so they don't have to actually consistently engage with collecting Zonaitems to do it, and then say the game just lets them instantly solve the issue by flying over it when the Shrines themselves hand you tools for the problems inside of them.
It's like BOTW where every test provides you with a #2 Pencil and a Calculator, but in TOTK people can just go to an easy to reach place and tell Hyrule GPT to build them a Green Goblin Glider so they don't have to actually engage with the puzzle, which is a bad thing on Nintendo's part because they don't ask you to actually use the items provided or ones you have in your inventory directly, but let you just use Zonaite to do it instead which turns into a free resource.
The game actually comes with a lot more of the "perceived" issues people had with BOTW like just being able to cheese the puzzles when very often you rarely get to deviate from an intended solution.
