So far, I only have about three villagers at the moment that are considered to be my OG villagers and they're Diana, Genji, and Julian.
Genji and Diana are not only my dreamies but some of my favorite villagers especially the former and they used to be in my New Leaf town. Julian, has been in my New Leaf towns since I also used to have two separate towns. Seeing him as the first campsite villager is great but also a funny coincidence in a sense. But I love him so it turned out great! xD
Still hoping to obtain some of the other main ones that I had which are: Marshal, Beau, Mira, and Chrissy.
I managed to get Ruby and Kabuki! I've had Ruby since Wild World (she'd moved out, sadly, but I loved her) and by a stroke of pure luck I got her in New Leaf; getting her in New Horizons cost me an arm and a leg, but she was well worth it because she's my favorite of all the villagers! Kabuki was just pure luck while island hopping, but I was so surprised and happy to find him. It low-key made my day!
Gruff, Sally, and Filbert were in my ACGC town. Lolly was in one of my NL towns, and Roald was in the other. He's going to be moving, though. Everyone else is a new face for me.
I kept most of my NL villagers and moved them to NH! Apollo, Marshal, Whitney, Beau, Phoebe. I had to switch out some of my other villagers for some of the new NH villagers such as Raymond, Judy, and Dom.
