Mario Kart 3DS producer wants the game to run smoothly in both 2D and 3D, online and offline.
Mario Kart 3DS producer Hideki Konno was questioned as to whether or not the game would feature online play. His response was "Of course."
Though the current online configuration is not quite set, he said that "our goal right now is to have the same number of players for both local wireless and multiplayer over wi-fi." The most important rule at the moment is ensuring that the game can run smoothly in 2D and 3D at 60FPS, both online and offline.
Mario Kart 3DS is scheduled to be released this holiday season.
