I think it is a great game - I'm loving the sandbox feel and the "anything goes" way of traversing the map, solving problems etc - but I admit it doesn't have the same sense of wonder and immersion (I think?) as BOTW somehow.
It's also the first time I've made use of any item duplication glitches (it seems like the only "fun" / non-grindy way of making use of the new building mechanic) so maybe that, plus being able to just fly around everywhere on DIY contraptions, has taken some of the fun / point out of wandering around the map 🤷♂️
I suspect that feeling of not having the wonder or immersion is because you played BOTW first so the novelty isn't there, I had never played BOTW so it was definitely wonderful for me
I've decided to try and find every bubbulfrog before I actually finish the game, I'm at the same point as you and I'm not ready to let it go! It's been so much fun.
(Might regret that by the time I get to the last few frogs haha...)
