One notable feature of the "Animal Crossing" series is the high level of customization available, some of which affects the outcome of the game. The player character is both named and gendered by the real life player at the start of the game, and their appearance can be modified by buying or designing custom clothes and accessories or changing the hairstyle (introduced in ""). The player's house can also be furnished, decorated, and later expanded: the player can purchase and collect furniture and place it anywhere in the house, as well as change both the wallpaper and floor designs. While its terrain, building locations, and initial residents are randomly generated when the game is first begun (except in "Animal Crossing: New Leaf", in which the player decides between four given towns, and "Animal Crossing: New Horizons", in which the player similarly decides between four given islands), the village's name and anthem, as well as some of the residents' catchphrases, are also determined by the player.
