And while Nintendo doesn't embrace it, they do support it. Nintendo provides free multiplayer online in many of their games. What they don't provide is online community in those games. You either play with your friends or you just join a game with random folks, and everybody is mute in the latter. It's minimalist, but it works.
This has its advantages; internet multiplayer is very much at risk from griefers and behaviour unsuitable for kids. And Nintendo are staying firmly pre-teen focused while leaving 'mature' gaming to the other two.
