Development
In a pre-E3 interview published in the July 2000 issue of Nintendo Power magazine, mentions that he is working on launch titles for the Nintendo GameCube, stating: "One title is really a new genre of game—what we are calling a "communication" game, which we hope to finish this summer." That game,, would be released a year and a half later in December 2001, two months after the launch of the GameCube in Japan, and eight months after. When questioned about upcoming Nintendo 64 games in a separate E3 2000 interview with IGN, Miyamoto states that he hopes to have "...a couple of new games for Nintendo 64 by the end of the year. These are not standard action-type games. We are calling them 'communication games'." This would suggest that and  may have been developed concurrently.

Despite being released near the end of the Nintendo 64's lifespan, sold through its entire print run. The success of the game, paired with the inability to produce enough cartridges to meet demand, encouraged the development team to port the game to the Nintendo GameCube with minor enhancements under the Japanese title. Taking advantage of the greater memory capacities of the GameCube, the team included new features that could not be added to the original game, such as Animal Island. The North American localization,, was released eight months later.
