I wouldn't number them.. on a one to ten scale, they're all above ten...
Except for Link's Adventure. It wasn't as good as the others. The Oracles are awesome; I still play them. Ocarina of Time was an awesome epic. Majora's Mask was a great psycological thriller. Wind Waker was very artistic. Link's Awakening was a great side-game. LTTP is amazing in every aspect. But.. Link's Adventure was kind of.. off. But still kind of good.
And we can't forget the CD-i Zeldas. Ugh.
