I believe the idea of the Wii is to unite all ages together. So that we can play together in FAMILY, with FRIENDS. And not like some selfish, anti-social person who only sees his game on the scrren and nothing else.
I have seen and had the first 8 bit computer (Spectrum,MSX,C64,...), then the 16 bit ones,.... until the Wii. And most of the games are playing alone, the multiplayer option game around much later.
I believe the Wii has made it to a great family-console. Where the most important thing is having fun. Like the old days where we all gathered round a boardgame (surely all the 30+ under us remember those days, right).
M$ has it completely wrong. They are just jalous, nothing more.....
and nothing less.
