I agree, Majora's Mask was the better sequel. But even though Wind Waker came 100 years directly after OoT, I don't see it as a sequel. I classify a sequel for Zelda as a continued quest, but I know what you're saying.

I kind of thought young Link actually was more mature in MM than OoT. He even looks different, and he is stronger.

TWW just showed us what happened after OoT, mostly in the Intro. I guess it is some what of a sequel in a sense.
