Nintendo has announced that it will be shutting down its Wii and DS online servers. The service, dubbed Nintendo Wi-Fi Connection, will be shut down on 20 May.
Many Wii and DS games rely on these servers for multiplayer gaming, which now won't be possible. More than 60 games will be affected worldwide.
Wii titles like Smash Bros. Brawl and Mario Kart will lose multiplayer, matchmaking and leaderboard support as they go offline permanently. DS games like Metroid Prime Hunters, Mario Kart and around 12 Pokémon games will also be affected.
At the moment all the games affected are listed on the official Nintendo sites for the US, Japan and Australia. The UK has not yet been added to the list, but it's looking like a worldwide shutdown will happen.
Nintendo will also end its Nintendo Video service for the 3DS on 31 March. The Wii Shop Channel and DSi Shop will continue working, however, along with the Wii's Internet Channel and YouTube app.
Sequels to Mario Kart Wii and Smash Bros Brawl are out this year. If users want multiplayer they're being forced to buy these.
