from SpaceWorld 2000. The movie these images are from was just a mock
up to show what the GCN is capable of. But Nintendo had been working with
the idea of a Zelda game using the realistic graphical style, as proven
by this quote from an interview with Shigeru:
"The reason we were able to show you the more realistic looking
Zelda battle at Space World 2000 in the summer was because we had been
doing some preliminary experiments with the console prior to completing
Majora's Mask. That's why that video existed."
