Better keep that sub up to date.
“Save data stored via the Save Data Cloud backup is available for as long as you have an active Nintendo Switch Online membership,” an answer reads.
“Classic games in the NES – Nintendo Switch Online collection and the save data for those games will not be removed unless the user chooses to do so manually. These items are stored locally on the Nintendo Switch system but cannot be accessed without an active Nintendo Switch Online membership.”
It’s a tad worrisome that Nintendo might delete your cloud saves if you forget to keep your membership current, but I suppose the trick here may be to auto-renew?
Moreover, cloud saves will not be offered for select titles including Splatoon 2, Pokémon Let’s Go Eevee and Pikachu, NBA 2K19, FIFA 19, Dark Souls Remastered and more.
Nintendo also used the FAQ to detail a one-week check-in that must be complied with in order to keep playing the Nintendo Switch Online service’s offering of networked NES games.
Nintendo Switch Online launches on 18 September, priced at $5.95 AUD for one month, $11.95 AUD for three months or $29.95 AUD for a year. A Family Membership costs $54.95 AUD for a year.
