redditでものすごい炎上してるけど、オンライン料金払わないとクラウドセーブデータ消されるの？
psplusのように6ヵ月保存してくれるわけじゃないの？(´・ω・｀)

Q. After my Nintendo Switch Online subscription expires, will my Save Data Cloud files and Nintendo Entertainment System – Nintendo Switch Online save data be erased?

A. Save data stored with Save Data Cloud cannot be kept outside of the duration of your Nintendo Switch Online membership.
Nintendo Entertainment System – Nintendo Switch Online also uses the Save Data Cloud, so the same applies.
However, if you keep the Nintendo Entertainment System – Nintendo Switch Online save data saved locally on your Nintendo Switch console, then you can use it again if you purchase another membership.
