Animal Crossing: Wild World is a 2005 social simulation video game developed and published by Nintendo for the Nintendo DS handheld game console.

Wild World focuses on living in a remote village populated with anthropomorphic animals, where the player character is encouraged to perform any number of tasks, such as collecting and planting. Like all Animal Crossing titles, the game is synced to the console's clock and calendar, allowing the game to be played in real-time, which affects the occurrence of in-game events based on the current time of day or season.

Like all the games in the Animal Crossing series, Wild World is an open-ended game in which the player assumes the role of a human who has moved into a village populated with anthropomorphic animals. During their time spent in the village, the player is able to perform a number of various activities, such as collecting items, fish and insects, or socializing with the village's residents.[6] The game is synchronized with the Nintendo DS clock and calendar, allowing the game to be played in real-time. For example, both daytime and night will occur in the village depending on the current hour, and snow will fall during the cold months. Different events occur at particular times of the year, such as holidays and the variation of collectible fauna depending on the month or season.
