Great post! I think I can agree with you. Maybe you have to point out that this is ONE factor that can lead to massive sales, but there are others.
But apart from that, I completely agree. Well, maybe I have another thing to ad: Why do you say that Mario 64 did not quite as well as Mario Bros.? I think 64 is the perfect example for that, you can do so many different jumps and yet it is so intuitive. When I got this game, I messed up a lot of time by only running around in the castle's garden and jump around.
And on another note, you're right with Miyamoto. I remember that he once said that the first thing he does is to settle the movements of the characters; the storyline and the objectives only evolve around that.
