A lot of times I think Nintendo gets really excited about a feature that has limited use cases, or is very kid-focused. And I think, "That's kind of cool and all but it's not really going to apply to me." Other times, the feature is so use-limited that I suspect it's Japan-centric. Like a carrying handle on the back of the Gamecube.
But then there's this. In which I can honestly think of no case, no matter how limited or specific, which would be superior to in-game services, or even a Switch app. I'm at a total loss. I'm baffled.
Honestly, seriously, if someone can describe any case where this is better or more convenient than built-in online features, I would be very interested to hear it. Because Nintendo surely must have its reasons.
