All animations were outsourced to a group of Russian animators because hiring animators from the United States would be too expensive (American animators were generally paid more compared to other animators during the early 1990s).
Voice actors were hired by people who were in union groups, or actors on the cheap.
The development team were only given one year to finish making the games.
This is understandable, from both Shigeru Miyamoto and also from a Japanese POV, it was not a good idea allowing a Western studio to mess with one of the Nintendo's core franchises without Nintendo's supervision. (especially in that time, taking into account all the mess regarding the SNES CD addon)
Recursive Adaptation: Link's obsession with getting a kiss from Zelda, and the portrayal of the King of Hyrule as a maniacal fat man and having the name "Harkinian", suggest that the developers had the cartoon in mind rather than the games.
On a side note, this is the first game where Ganon appears not as a blue boar monster, but as a dark-green-skinned warlock with green/red/brown cape. Hello, Ocarina of Time!◊
What Could Have Been: In one cutscene in Wand of Gamelon, Zelda is seen wearing the same outfit she wore in the Legend of Zelda cartoon. It's highly likely that, at one time, the game was meant to tie into the cartoon.
