Yeah the video seems to be selling a use case that likely isn't very common. How often are people going to go a bar and sit around a switch playing video games? Maybe once or twice? I imagine the dominant gaming habits are what Xbox/PS focus on (one person in a room, possibly connected by internet to others).
I dunno. The Switch seems to have a lot of focus on local multiplayer. And with how portable it is, I can definitely imagine heading over to my local gaming store to find someone else that I can play with.
