The Nintendo Switch Online service has a collection of classic Nintendo game releases readily available for everyone to play. Depending on whether one gets the Expansion Pass or not, there is a large selection of retro games to play that people have loved over the years. While the Nintendo GameCube classics section recently started alongside the release of the Nintendo Switch 2, the company has plans to add more GameCube t**les to the service for subscribers to have access to. But for Nintendo fans to really take advantage of the service, and for more people to join, Nintendo needs to add more multiplayer GameCube t**les to the library of Switch Online classics.
