Nintendo Switch debuted last Spring and it’s hard to believe it lacked a proper online service. It’s finally ready for debut, come September 18th. This service lets you save game data to the cloud and even play some games that are available to subscribers, like the PlayStation Plus does.

At launch Nintendo is offering 20 games, like The Legend of Zelda, Donkey Kong and Super Mario Bros 3. The Nintendo Switch Online Service gets activated on Tuesday, September 18th. Subscribers will be able to sign up for a 7 day free trial and afterwards they will have to pay cold hard cash. You can pay $4 for a month, $8 for 3 months or $20 for a year. That’s waaaay cheaper than both the PlayStation Plus and Xbox Live subscriptions.

There’s also the option of a $35 a year family plan, available for up to 7 users. Nintendo is holding an event this week to reveal more details about the service, plus extra info about games. Keep in mind that the Nintendo Switch Online service will lock Switch user profiles to their linked Nintendo accounts.

This means that over the next week you should properly associate accounts. It will be interesting to see if Nintendo also offers some other games aside from the 20 ones at debut time. Monthly games would be nice, but the price is too low for that. Classic NES titles are lined up for the special offer.
