GameCube online functionality

The GameCube has limited support for online gaming. Nintendo never commissioned any servers to interface with the console, but allowed other publishers to do so. The only games released with internet-based gameplay modes were Phantasy Star Online, Phantasy Star Online Episode III: C.A.R.D. Revolution, and Homeland. Nintendo also published three racing games with local area network (LAN) support: 1080° Avalanche, Kirby Air Ride, and Mario Kart: Double Dash!!. Using network functions requires the official broadband or modem adapter since the console does not have out of the box network capabilities.

Despite competitors Microsoft and Sony advancing online gaming for their consoles, the Xbox and PlayStation 2, Nintendo remained pensive with its online strategy for the duration of the GameCube's lifespan. Company leaders including Shigeru Miyamoto and Satoru Iwata based their stance on concerns with maintaining quality control over their games and doubts that players would want to pay subscription fees.
