The Nintendo Wi-Fi Connection was succeeded by Nintendo Network on the Nintendo 3DS and Wii U. With GameSpy, who provided servers to Nintendo, being dissolved, the Nintendo Wi-Fi Connection was discontinued on May 20, 2014, making online play in Nintendo DS and Wii games unavailable through official means.[1]
Below is a table of all online features in Animal Crossing: Wild World and Animal Crossing: City Folk that used the Nintendo Wi-Fi Connection. All of these are unavailable through official means following the discontinuation of the Nintendo Wi-Fi Connection on May 20, 2014.
Some online features in City Folk instead used the WiiConnect24 service.
