I think that New Horizons has less charm than New Leaf overall but it still has some charming elements to it. I do wish we would see updates that would bring back some of the New Leaf aspects, though! From New Leaf I really miss the following:
-Retail! I miss Reese and Cyrus tons. I'm not sure what purpose Cyrus would have since we can customize things on our own - maybe he would be the one able to customize Nooks Cranny furniture?

I miss Reese and Retail, though. I thought it was a cute idea and I like how she paid more bells for my stuff, lol
-Nook's Cranny getting upgraded. I genuinely can't understand why Nooks doesn't upgrade
at all. I'm not saying it needs to have the same upgrades as New Leaf because I'm not sure the big emporium would suit island life but the fact
nothing changes? That bothers me. I remember being so excited and intrigued when I first saw the shop being covered up in New Leaf! And it helped make me feel like I was progressing in the game getting to see new shops open and the Nookling's shop get upgraded. Plus with the upgraded shop we would be able to see Gracie come back and get all her furniture sets which would be nice.
-More shops in general, honestly. I don't enjoy the mechanic of having Kicks & Leif be pop up guests who comes sporadically to sell stuff or having Labelle be a fashion checker. Like Nooks, I wish we would see Able's upgrade. It doesn't need to be a huge upgrade but I was really let down when I realized Labelle's fashion checks didn't lead anywhere. I would've loved for her to move back in with her sisters! With Kicks & Leif it's the same feeling. I was waiting for the day when they'd say, "wow! I'm pretty popular here on the island I think I'll open up shop," but that never happened. Neither of those NPC's need to have
big stores and I think it would be charming to have a small garden shop like Leif's first New Leaf store and Kick's little shoe store. I'm not sure where Dr. Shrunk would fit or what his role would be since we get reactions from villagers so I could go either way on his inclusion, honestly.
-Snow family. I think the whole snow family in New Leaf was adorable. Excluding them in favour of us
only being able to make a snowboy in various sizes was a bummer, honestly. I loved having the little snowtyke, snowmum, snowdad,
and snowboy. It added variety when I was trying to make snow people! They could've kept the core mechanic the same (ie: getting a DIY & big snowflake for every perfect snow person) if they really wanted too but it would've still been nice to have that variety.
-I think the music in New Leaf was more charming but I know that's a person preference thing. I just feel like New Leaf's music is more calming/relaxed which suits the atmosphere of the game better.
-Brewster's would be nice to have back as well! I didn't understand how to play his mini game, lol but I miss having the coffee shop and getting to walk around with a to-go cup of coffee.
-Phineas The Badge Man! I miss him. I know we get our badges through the Nook Phone now but there was something so whimsical and fun about having Phineas come to visit.
-Post Office. I miss the post office and all the postal workers. The small postcard rack in the airport is not a stand in for the post office.
-Dialogue. I'm not saying I want the villagers to be mean to me - because I don't. I really don't mind at all that the villagers are all really sweet and friendly, lol. But that's not an excuse for the dialogue to be as bland and repetitive as it is. New Leaf's villagers were
also really nice to the players but at least their dialogue had a little more variety. They'd ask me to play games, invite me to their house/ask to come to mine, randomly ask me questions out of a magazine quiz they read, and just in general it didn't feel like I was seeing the exact same dialogue every day. It wasn't perfect by any means but that meant that New Horizons should've been
better. It should've built off of the New Leaf dialogue but instead it feels like we took a step back which is odd.
-I hate the tools breaking. I hate it. Part of the charm of Animal Crossing is catching bugs, fishing, gardening, etc. It's
not charming for my tools to break when I'm in the middle of watering my flowers or catching butterflies.
I feel like New Horizons got stale a lot quicker than New Leaf did, at least for me. That's not to say that New Horizons doesn't have it's charms or positive aspects to the game! Because it certainly does. I just feel like when you weigh both games against each other New Leaf has
more charm, more whimsy, and more creativity thrown into it. When I look at New Horizons I see a lot of, "almost great" ideas. I don't know if it's that the game needed more time in development or if the developers decided to favour make the game more like a dollhouse (just placing pretty things together) and less like an actual little alive island. I barely talk to my villagers anymore because they're always saying the same thing. I can't interact with most of the furniture I've placed. It's not as enjoyable to fish, catch bugs, or even garden in this game. I'll do those things still but it's not as fun and calming as it was in New Leaf.
