GameSpy is ceasing hosting of online games on May 31.
GameSpy, owned by Glu Mobile, was the basis for Nintendo's Wi-Fi Connection services and their closure gives a reason as to why online play for games on Wii and Nintendo DS are ending. This not only affects Nintendo games but also many other games on different systems which used GameSpy for their servers. According to the GameSpy website, it will be up to the publishers to decide if and how online services will continue.
Nintendo games affected will all be ending their services on May 20, a little more than a week before the GameSpy shutdown.
