Earlier this week, Nintendo finally revealed their plans for their online subscription service. Dubbed "Nintendo Switch Online," this service will be required when it launches in September in order to enjoy online co-op with friends for current titles, like Splatoon 2, and future ones as well. Other than the official name, that's nothing particularly new. What is new is that getting that subscription will also give you access to a library of classic NES titles that will include online capabilities for those that support multiplayer.
