Nintendo officially revealed the Switch’s paid online service. The service is $20 a year. Online play will be available, including 20 NES games with online play. More games added regularly. The Legend of Zelda, Mario Bros., Super Mario Bros 1 and 3, Dr. Mario, Donkey Kong, Ice Climbers, and more will be revealed. Service also will have a save data cloud back-up. This is probably the most asked for feature as one of the largest complaints at launch being that if the system is damaged all of the save files are just gone. Service launches in September and will be required for online play.
