I mean, it was fun and nice, and I'd rather have it in NH than not if there was a choice - but I don't think anybody feels New Horizon is incomplete due to its absence (especially since it came so late in NL's life).
I have all the amiibo cards and figures, and know exactly what items came with them.
The RV cards (series 5) was a set of 50 cards.
Honestly, I can name a few hundred items (most of them customizable including food) I really miss, just off the top of my head, and the RV's provided a great deal of them.
I paid a lot for those amiibo's, and didn't think they would be a 'one and done' deal.
They should be more useful than what they are in NH.
Reguardless, I won't be happy unless we get some, if not all, the items back.
It's all well and good to give you an entire island with the option to put items outside, but then to omit so many items that would've been worthwhile putting outside is just baffling!
Imagine having all the food items, plants, furniture sets, totems, posts (pantheon etc) hay bales, tractor, crates, fairy bottles, beacon fire, poogie, zen chairs, box seat, luxury car, round beaded cushions, oh, the fancy tea set was also awesome.
I miss the brick counter, the bread making set, bread basket, cheese, tarts, cupcakes, veggie basket, stew pot, milk canisters, K.K.'s guitar case that clicked open, the interactive watermelon, etc.
Oh, pirate armor, and plate armor, jomon pottery, drip pail, wheat grass, sarcophagus, all the drums like timpano and conga, creepy bones, the merlion and african mask!
Mannequins.. the windmill, zen bell, trellis.
The HHD giant furniture.
So many items.
