The most popular ad-hoc wireless game feature for Nintendo DS is the Chance Encounter mode of Dragon Quest IX (Square Enix, 2009), which exchanges information between player''s games, and has been used 117,577,073 times as of 4 March 2010. The system uses wi-fi to search for other players when the game is being carried around in public place (like the Tokyo Metro or just busy streets). When it finds another player, information is exchanged and new gameplay options are made available to both players. This information is effectively viral, as the consoles keep track of everything they''ve received and then send it on every time they have a Chance Encounter.
