That's what came to mind for me as well. The games have some fantastic elements, but a lot of the gameplay loops are designed to be slow.
I recall reading that preventing 'assembly line' mechanics was a deliberate choice. As a result, in New Horizon you can't do bulk crafting, you need to perform multiple button presses and watch an animation for every single one.
Shopping is equally bad, where buying stock from a visiting NPC takes orders of magnitude longer than it might in an RPG, because you need to button through multiple pages of dialogue after each purchase.

I've sold my copy of Animal Crossing because I felt it did just that: wasted my time on meaningless repetitive tasks
