The 3DS debut of Mario Party, coming to North America on November 22, will not feature any online multiplayer, according to a Nintendo representative at a recent demo event. Mario Party: Island Tour will, however, be fully playable using one card in Download Play.
The third portable entry in the nearly 15-year-old franchise features 80 mini-games that can be played individually or in one of the 7 game boards. It will also use AR Cards for mini-games and feature StreetPass, though the extent of the StreetPass is unknown as of now.
Mario Party: Island Tour is slated for a November 22 release in North America, a winter 2013 release in Japan, and a 2014 release in Europe.
