I had this game a long time ago. I didn't play it, but instead, had watched my brother play it. I had tried to play it before, but was dumbfounded by many aspects of the game. Later, I had went to go and beat it by myself, but had ignored most, if not all of the sidequests. Because of this, I kind of thought that Majora's Mask was an extremely short game. I never realized that there was this much backstory or morals.
One thing I know for sure about Majora's Mask, is that the Side Quests make up most of the game's backstory and gameplay.
