"Animal Crossing: Wild World, named Oideyo Dōbutsu no Mori (おいでよ どうぶつの森, lit. "Come to Animal Forest") in Japan, is a video game published and developed by Nintendo for the Nintendo DS handheld game console, and the follow-up to Animal Crossing for the Nintendo GameCube.
The main gameplay of Animal Crossing: Wild World involves maintaining a small town. In addition, the player has the opportunity to engage in a variety of tasks, such as interacting with villagers, planting flowers, and collecting items such as furniture, clothes and fish. Animal Crossing: Wild World is non-linear and does not require the player to pay off their house mortgage, although it is one of the game's main goals. "
