When it comes to Tom Nook's backstory, it's one of the most extensive in the Animal Crossing series, especially as it relates to Sable, the main character. Villagers and special characters are the most common types of characters in the Animal Crossing series, and they can be divided into two categories. In the game, villagers serve as the player's neighbors, moving into town and acting as citizens there, frequently requesting favors from the player or conversing with other villagers at various points during the animal crossing bells. Special characters are encountered less frequently and only appear during specific holidays or events, though some of them do live in town and run the businesses that can be found in the town center. In Animal Crossing, Tom Nook is one of the most well-known recurring special characters, and he also happens to have one of the most well-developed backstories in the entire franchise. Animal Crossing, like the previous installments in the series, has remained largely unchanged in terms of art style and the high degree of freedom of play that is built around the collection and construction system.
