Nintendo typically offers fewer titles when launching its console but strives to introduce new types of games that feature its popular characters.
Competitors plan to feature Internet connections in the autumn.
Although GameCube is built with the hardware to connect to the Internet, Nintendo has not announced plans to sell a connecting device for Internet online gaming. Nintendo has a loyal base of gamers who grew up with the original Nintendo system. Yet, in 1996, Sony, a newcomer to video games, was able to take Nintendo by surprise and topple it from its dominance. Sony's PlayStation and its successor now enjoy a 60-percent market share in American homes. But Nintendo says it will not be taken by surprise again.
