nintendo wifiNintendo has announced that it plans a worldwide shutdown of the Nintendo Wi-Fi Connection services in the coming months.

The shutdown means that a number of online services on the Nintendo DS, DSi and Wii will be unavailable after the 20th May this year. The decision primarily affects online play, leaderboards and matchmaking services.

This means games such as Mario Kart Wii, Super Smash Bros. Brawl and Animal Crossing: Let’s Go to the City on Wii and Metroid Prime Hunters, Advance Wars: Dark Conflict and a vast number of Pokémon games will be losing their online functions.

Nintendo has given a full list of the games affected by the closure across the UK, Japan, US and Australia on each regions specific official site.

Not all will be lost in the service termination, as Nintendo said some services will be available after the 20th May:

• Internet Channel
• Nintendo DS Browser
• Nintendo DSi Browser
• Nintendo DSi Shop
• Nintendo Wi-Fi Connection Pay & Play
• Wii Shop Channel
• YouTube

The Nintendo Wi-Fi Connection service was introduced as an alternative to the PSN and Xbox Live services provided by PlayStation and Xbox, and was then integrated into the Nintendo Network when the 3DS was released back in 2011. The Nintendo Network used on the 3DS and Wii U introduced a number of social features to the consoles.
