Until 2013 GameSpy was a service which made it possible for the players of computer games of a variety of publishers to play online rather comfortably. For some of those games' online play the GameSpy network was essential, e. g. Stronghold Crusader, Conflict Global Storm, Conflict Denied Ops or MoHAA. GameSpy continued the „fine tradition“ of closing down required networks, like the WON also did.
