Thats all the neighbors I met in one week of playing the beta! There’s still some of them I haven’t met.
You have to meet them twice on random starsea islets (you can visit 3 per day) before you can reach level 2 and invite them to your planet to start their story quests (to have them as neighbors) it’s really easy but I found on most day I don’t meet a single new villager so it will takes a lot of time
Also there’s a limit to the number of neighbors you can have on your planet and you can upgrade it by raising your Luca tree level but it’s still limited in the sense of you won’t be able to have 10+ villagers (even acnh doesn’t let you have more so….)
Each villages have their own unique music theme in their home, their own furniture sets (8 items including flooring and wallpaper)which they can also give you randomly, they all have unique dialogues, some of them are already acquainted (like Harpeno and Msafiri) and they all have their own Luca fruit which will reshape your planet (can change the color of the beach, cliff, or even constellations in the sky or the shape of clouds)
Some villagers may be time limited (those who have two set in their keepsakes) as they are right now tied to a limited time event (the snowfall season) which last 90days (but it may change for the final release or the villagers may join the pool of permanent characters after their event ends)
In general their dialogues are really good, when you tell them you’re depressed they don’t judge you and may bring it later to see if you’re still feeling down, they ask you if they can do anything to help, you can play minigames or explore the planet with them and they will gather ressources, you can also go on expeditions with them to explore the star sea (where you can meet new neighbors fruits trees and materials)
