Here's what I'm trying to manifest: (Unrealistically)

I hope the new amiibo pack means they're bringing back old characters &/or adding new ones. Maybe Porter/Champ make returns somehow in that.

More requests, for example: when they would make us get signatures in other people's towns/ask us to cut a tree down in a friends town for good luck/ bringing Katie back to Kaitlin - that would add some spice to the lack of multiplayer fun.

I hope they add more subtleties like in City Folk if you took the bus and didn't click through the dialogue for awhile, Kapp'n would eventually start singing his sea shanty.

I want to unlock things as we progress through the game like filling our museum, buying lots from the shops, etc. But I'm not talking just nook miles because they are mostly useless in game because of the lack of things to buy with them, and if you have a full island the mystery islands aren't all that valuable nor interesting. It would be so nice to see them upgrade the nook miles shop to maybe include being able to purchase special character buildings or exteriors or something.

Nooks special items, 50% off days, monthly lotteries, nook points. Upgrades.

Harriet, shampoodle, wigs. (She was my favourite NPC)

Exterior building customization like NL, possibly connected with HHA this time.

I miss the train/bus/kappn's boat that had relaxing dialogue.

I don't just want the villagers to tell us wacky stories but to positively affirm us like in previous games lol, I think part of that was what made the connection to the villagers feel deeper and more meaningful when they would teach us little positive life lessons.

Villagers sharing things more often and showing letters to one another and having it come back to you or something lmao.

Villagers remembering things and starting rumors about the player again.

Villagers doing things in groups away from the town hall.

Katrina, feng shui, the lovely phone, luck, and charms.

Perfect & Island fruits.

Gracie and more furniture sets.

Wishing well/more community spots (maybe being able to create and place them)

To be able to visit Lyle at the HHA building and have the rating actually mean something.

Flea market/Auction house/Retail equivalent.

More plants, growable or otherwise.

Pocket-Camp-level items and interactivity with them.

Dr. Shrunk!!

Blanca, Rover, Pelly & Phyllis not just in the café, but in game. (Wishful thinking) In the café would be lovely too.

Constellations and the observatory. Celeste knowing & being able to relay info about stars/constellations like Blathers about the rest of the museum.

Resetti and Don usefulness, maybe their hideout under a manhole again.
I'm just hoping they're finally taking our feedback knowing that some long time fans of the game are a bit disappointed and have low hopes for the next game to come, feeling like the franchise has only become a cash grab for Nintendo.
