Mario Kart: Double Dash!!
Double Dash!! was first shown in 2001. People saw Mario and Luigi driving their karts on a flat floor for seven seconds. It was being made and was basically Mario Kart at the time. In April 2003, Nintendo showed pictures of the game and said that the game would be called "Mario Kart: Double Dash!!". In 2003, some people were able to play a demo of the game (not all characters and tracks were in it). New things, like having two characters drive one kart, had been added. A new demo with some new things was shown at the Games Convention in August 2003. In September, Nintendo showed people a nearly complete and more sped up version of Double Dash!!. The Gamers' Summit also said that the game would be out in North America on the 17th of November, 2003.
