Completed game, it doesn't feel like a BOTW DLC at all. If anything it makes BOTW feel like a tech demo for this game. Game is legit a technical marvel, keeping track of that many physics objects on potato hardware and it not breaking is really impressive. There are a bunch of decent gameplay loops, my only complaint would be that it can be a bit grindy at times... but also it's Japan so who's surprised?
Ultrahand and zonai devices offer countless ways to tackle almost any part of the game, my gameplay experience was almost nothing like my gameplay experience in BOTW. If anything, by the time I got to taking on Ganon I'd just fully forgotten normal combat mechanics because most of the game I spent using various engineered solutions to every problem up to that point. If you have a problem-solving mindset it will probably be the most fun you've ever had in a video game. Sure, you can play it just like BOTW if you want, but I don't see why you would. It's much more fun to roll into a clump of enemies in your tank/chopper/orbital deathcannon surrounded by a set of autonomous laser roombas.
