Nintendo Switch Online (NSO) launched in September 2018 as Nintendo's subscription service for online play and retro game access.
At launch the service included a library of NES titles alongside online multiplayer and cloud save support.
Over the following years Nintendo expanded that core offering into a wider retro catalogue and introduced new membership tiers and exclusive multiplayer experiments.
From NES to multiple classic libraries
Nintendo has steadily grown NSO's classic game libraries.
The SNES library was added in 2019, and in 2021 Nintendo introduced the paid Expansion Pack tier, which broadened the service to include additional past-platform content.
By 2026 the NSO catalogue lists games and systems spanning the NES and SNES eras through later portable and home consoles, including N64, GameCube, Game Boy family systems, Game Boy Advance, Virtual Boy and SEGA Genesis releases.
The service also features online-focused titles, most notably Tetris 99, which launched for NSO members in February 2019, and F-Zero 99, which arrived as another NSO multiplayer exclusive in 2023.
Features and platform context
Alongside retro libraries, NSO continues to provide online play, cloud saves and eShop connectivity for Switch owners.
Nintendo has used Nintendo Direct presentations and dedicated announcements to outline expansions to the service and to highlight new content and functionality.
Community voices on the service and games
Community members shared what they are playing and how NSO fits into their broader habits.
César Tribst reported finishing Darksiders, Shadow of the Tomb Raider and No More Heroes 2, and said he completed Fire Emblem: Three Houses DLC while planning to play titles across platforms, from Resident Evil 4 Remake on Xbox Series S to Fire Emblem Radiant Dawn on Wii and Metroid Prime 4 on Switch.
Another user, PanurgeJr, said they had spent years on the Xenoblade series and recently started Stellar Blade on PS5 while enjoying multiplayer content like Splatoon Raiders.
FrozenTundra88 described alternating between Splatoon Raiders, The Legend of Zelda: Tears of the Kingdom and Donkey Kong titles, and mentioned a return to seasonal horror games for October.
As Nintendo Switch Online approaches a milestone anniversary, the service stands as a central part of Nintendo's online and retro strategy, delivering preserved classics and occasional live multiplayer experiments.
