Since its launch in September of 2018, Nintendo Switch Online has gained over eight million subscribers, not including free trials.
During Nintendo’s financial results briefing, it revealed the milestone for Nintendo Switch’s online service and said that it is “working on continuing to expand the service offerings.”
While it currently provides subscribers with such features as cloud saves, online play, and an ever-growing library of NES games, there have been reports that SNES games may be added to the service in the future.
