Animal Crossing New leaf! My big brother introduced Animal Crossing New leaf to me and my younger sister in 2018. I have pure nostalgia for this game and me and my younger sister love the Animal Crossing New Leaf music. I still play Animal Crossing New Leaf and my younger sister.
New Horizon's was the first game I was introduced to the series and then New Leaf sometime after. I'm glad I did as it's a fun game to play whenever I'm in the mood for it.
New Leaf was my first Animal Crossing game :^) I got it really young, around six, since I spent a lot of time in waiting rooms due to various reasons. All I did when I had it back then was hit villagers with my net, cut down trees, and start beef with random villagers lol (boone suffered under my oppressive rule).
