Villagers and Animal Crossing, believe it or not, have characters. Different characters have appeared in the game since the series' inception, but villagers have adapted over time. Certain game systems in New Horizons are dictated by the identities of the villagers. If you talk to enough neighbors with the same attitude, you'll notice that the conversation for contrasting scenarios is almost the same. If you spend enough time with the animals, you'll see that the villagers with the same personality will welcome you, thank you for a gift, and respond to your stung face in the same manner. Depending on the case, each personality has a different dialogue encoded into them. This is valid in all face-to-face encounters and letters in the mail. The developers pre-wrote all of the dialogue. You'll find the same interactions between yourself and villagers with the same personality if you play enough during the day. The architects seem to have wished for us to have a diverse range of characters on our island in order to diversify the discussion topics.
Each personality has unique traits that influence how the villagers live their island lives, such as what time they go to bed, how much they gossip, which other personalities they get along well with, and how they treat you as the player. Cranky peasants, for example, will take some time to warm up, but once they do, they become some of the friendliest neighbors. Sisterly villagers will give you relaxation advice, cheerful villagers will always be happy to see you, and lazy villagers will enjoy snacks.
Any other explanation could there be for having multiple personalities on your island? The main purpose is to get responses. Each personality type is associated with a series of reactions. You must have at least one of each personality on your island at any stage during your playthrough to collect all of the emotes available in the title. Every now and again, they'll approach you, tell you about a certain response, and then show you how to use it yourself.
There are a total of 40 reactions available this way, with the fifth and final emote for each personality available only if you are best friends with a villager with that personality. The remaining 19 responses can be obtained by buying them or attending holiday activities. Who shows up at your campsite will still be determined by their personality. Your first campsite villager will still be chuffed. Following that, the villager who arrives in your campsite has a 50% chance of becoming an animal with a personality that you don't already have on your island. and a 50% chance of any personality appearing. If you just want to find Raymond and don't want to go villager searching, keep all the smugs off your island and he'll have a better chance of showing up in your campsite. According to Nookipedia, each personality in New Horizons is associated with two distinct subtypes. These primarily consist of two hobbies with distinct dialogue that the player can encounter after they achieve a high degree of friendship with the villager. It's unsurprising that the neighbor conversation gets rusty and boring after a bit. Nintendo also used new dialogue in many of the patches. A lot of ACNH design slots is about a forthcoming celebration or about new furniture or clothes that we get for the new upgrade. We do, however, require variety. The repetition would not have been as apparent if we hadn't been trapped indoors during the pandemic with only Animal Crossing to play, but it was because we were. We spent a lot of time on New Horizons repeating the same sentences over and over. We're not game developers, so adding new dialogue isn't difficult. This is something that the original Animal Crossing does more than any other game in the franchise. People enjoy conversing with their neighbours. Gamers enjoy constantly seeking them out, talking to them, seeing what they're up to, and seeing if they have something that needs to be done.
The extra dialogue for each personality could help us vary our time and make our everyday lives less monotonous and repetitive. The idea that we all have different characteristics is certainly a bonus, but a little more will help us get along well with our neighbors.
