You forgot a pretty important one: they did all this AGAINST the general gamers opinion.
The opinion was against them all this time, and, guess what, STILL is.
That's what's even more amazing to me.
I recall back in 1991, people already wanted to get women into games. They never really succeeded in a big scale, except the Sims perhaps. When you look at the situation, you understand the videogame industry would never have achieved that without Nintendo. Because the current situation shows that what needed to be done is what Nintendo have done, and the consensus was against Nintendo all the time, and still now, there are a lot of people that can't accept what Nintendo has done, they call it "destroying gaming".
Man, I can tell you, nearly all the things you cited garnered bad press, kilometers long threads of hate, on videogame forums, when they appeared. To later manage to be huge successes in real life.
People are also quick to dismiss, or absently forget about the dangerous decline in the Japan videogame industry. Nintendo basically saved their core market in Japan, and made it thrive even more to boot.
I had the "chance" to be a lapsed gamer when I started noticing that in mid 2005. I couldn't understand all the hate, but didn't care at all. With my external view of this, I couldn't believe all the hate piled up on Nintendo. I think the worst was when the Wii name was announced.
I said I had the chance to have an external view, because it allowed me to not be blinded like I saw all the haters were at the time. The haters were describing a future completely opposite to what I saw with my fresh eyes of lapsed gamer.
I was shocked at the time, because I thought to myself: "the disease I saw years ago in reviewers has crept on all the gamers". Fortunately, the haters were not all of the gamers.
But reviewers still have this disease they had years ago, and the Wii is just making it even more apparent. Sad...
