Well i checked out the app, requires 9.0 or later so my iphone being a gen behind is too old to be allowed to download it. So my options are buy a new phone that costs more than a switch or like a sane person laugh, say fuck that and use discord,mumble, team speak or even my goddamn PS4 party chat to play with friends.
Personally i dont see the win here for nintendo. I know i can just grab any number of free programs and do the same but the average consumer knows shit about fuck all when it comes to technology. Are they really expected to buy a console, buy the games, buy additional overpriced controllers for local multiplayer THEN buy a new smartphone more expensive than all that put together WITH a yearly subscription fee added on top?
After the mainstream having no goddamn idea what the Wii U even was they really think the same crowd is going to be down with all that?
Which means the more technically minded people get around it, the mainstream will be confused and not bother, so who is the audience?
