An anonymous reader writes "For over a decade, GameSpy has provided and hosted multiplayer services for a variety of video games. GameSpy was purchased in 2012, and there were some worrying shutdowns of older servers, which disabled multiplayer capabilities for a number of games. Now, the whole service is going offline on May 31. Some publishers are scrambling to move to other platforms, while others are simply giving up on those games. Nintendo's recent abandonment of Wi-Fi games was a result of their reliance on GameSpy's servers. Bohemia Interactive, developers of the Arma series, said the GameSpy closure will affect matchmaking and CD-key authentication."
