The way I see it those earlier updates were that the game wasn't finished by release date so they had to save a bunch of stuff for later. The 3.0 update, OTOH, is a not-so-subtle 'Hey you guys, look at the new shiny, now you'll just HAVE to buy the Switch 2!'
Yes, the different personality types give different recipes. And there's already a way to boot out villagers you don't want providing someone you do want shows up at the camp site. Sure, it takes some patience and it's not completely fool-proof but it is in the spirit of Animal Crossing.I would LOVE them to add the ability to kick out a neighbor that you dont like or want anymore.
I've asked the web about this and I've read that kicking out villagers and replacing them with a 'different class villager' *like a sister for a grumpy etc etc* gets you different recipes.
I've been trying to boot out a particular resident for a year and she will not leave! im even top level friends with her and keep giving her gifts and she's just being stubborn lol! I've even tried being mean to her and then best friending her again!
