I was actually complaining to my FC the other night about these quest.

SE Quest Designer Guy (QDG) #1 Hey Yoshi! How bout an epic quest where the player has to find some moogles that are hiding!

Yoshi: That sounds like a great idea!

(Short while later)

SE QDG #2 Yoshi! I got this great ques where the player has to find some moogles that have been lost!

Yoshi: Hmm, that does sound good although vaguely familiar..

SE QDG #3: Yo Yoshi, so I was thinking bout this quest where the player had to find these Moogles.. (continues on)

Yoshi: Um... Sure. Deja Vu..

This goes on for several hours, somehow making it into the game.
