Could not play a single game online without it feeling like torture. A 2 minute match could take over 10 minutes.I had minimal problems on the Wii U with Mario Kart 8 and Splatoon. Both those games were fairly stable for me. Smash was better than Brawl in terms of connection stability, but still not good enough for me to play online.
The hope is that now that we have to pay, the servers will be more stable and the gameplay will be more enjoyable. I don't mind paying $30 for that.
more n likely it's just pay to play online. If you have to pay to download games...that'd be ****ing ******** (but not unlikely for Nintendo to do tbh).
Online Play on Nintendo Switch
You’ll be able to play compatible co-op and competitive games online by signing in with your Nintendo Account. Online play will be free for Nintendo Account holders until our paid online service launches in 2018.
After the free-trial period, most games will require a paid online service subscription from Nintendo in order to play online.
This service is only for Nintendo Switch. It does not affect online play or features for the Wii U or Nintendo 3DS family of systems.
Online lobby and voice chat
Our new dedicated smart device app will connect to Nintendo Switch and let you invite friends to play online, set play appointments, and chat with friends during online matches in compatible games─all from your smart device.
A free, limited version of this app will be available for download in summer 2017.
Classic Game Selection*
Subscribers will get to download a compilation of classic titles with added online play, such as Super Mario Bros. 3, Balloon Fight and Dr. Mario.
