I found the following quote in the book "Game Over: Press start to continue" by David Sheff. Under the chapter "I. Mario", it starts with the following from Shigeru Miyamoto:
"What if you walk along and everything that you see is more then what you see- the person in the T-shirt and slack is a warrior, the space that appers empty is a secret door to an alternate world? What if, on a crowded street, you look up and see something appear that should not, given what we know, be there? You either shake your head and dismiss it or you accept that there is much more to the world then we think, Perhaps it really is a doorway to another place. If you choose to go inside you might find many unexpected things."
I think the current attributed quote should be changed into this one.
It's so similar...it doesn't really matter. i think the other one is more mystic. it's up to you really.

"I don't know what Mario will look like next; maybe he will wear metallic clothing." - 1991, before the release of Super Mario 64.
This almost certainly cannot be right, one way or the other, as Super Mario 64 was not released until 1996.
1991 was indeed before 1996, last time I checked.
"I don't let Mario just appear in any kind of game. Mario could not appear in Zelda games. They are two distinct game worlds." - I saw that and I thought it was quite funny. In Link to the Past for SNES, you saw a picture of Mario on a wall,w hich when you yanked gave you a number of rupees.
In the Legend of Zelda: Ocarina of Time, Mario has pictures on the inside walls of the castle.
I think he meant the character, not his image. Heck, malon and Talon wear Bowser pendants.

- We don't pay a whole lot of attention to the Internet until people have played the game - then we pay a lot of attention to whether people liked it, ... We read through it and see it, but we don't take it into consideration. ... [The Internet] is not going to dictate the direction of where the game goes.
- We've just finished that, but we can make it better!
- What role does realism play in video games I ask myself. Is this image more interesting? Sometimes.. however, what if a "detailed" hand with 5 fingers is catching a bottle but the fingers pass right through it? Is this still realistic? Rather than to show each meticulous and tiny detail of a finger, it is more important to make the end action look more credible by working on the movement and functionality of the arms and the hand in relation to the object.
