Nintendo have confirmed that roughly 10 million are now subscribed to Switch Online. The number is even more impressive if we take into account that the service was launched less than a year ago - in September.
With a premium online service, players can access a lot of additional content, including new multiplayer modes, save game files, and even the classic NES games. The lineup is already quite impressive and it includes some legendary titles like Metroid, Donkey Kong, the two Zelda games, and of course, Mario games.
SNES games are not included yet, but hopefully that will change in the near future. One can hope!
