Nintendo's online. A game to keep whilst subscribed or a game rotation?

I wonder how they are going to justify a paid online subscription. Even if the service is great, will they have enough games that even has online? I mean the PS4 and XB1 gets many every year. I don't think Splatoon 2, Mario Kart 8, SSB and a few SNES games is going to be worth it.
