@Cozzer has a good point.
After all such games profit for being the main subject of conversations all over the internet. When was FF8 released? It was long ago. We still talk about it. This is a product of modern art in my opinion, part of many cultures merged together.
In my opinion such scenario holes exist for two reasons.
1] To create fruitful conversations people will enjoy discussing.
2] To create spinoffs in the future based on the main game. For instance Final Fantasy Crisis Core. We knew nothing about Zack but basic info. Then that game hit the market, BOOM! Success. Everyone wants to know just a little more of what happened back before FF7.
As long as there is not something clearly defined by the artist, it means that the artist lets it loose to interpretation.
She/he probably does that intentionally, so the audience will have to interpret it. That's always my personal opinion I might be wrong here.
But when I wrote one small story, I had described the main character in detail.
Then some side characters were described in general intentionally to make the reader's fantasy play with their mind.
Like:
"Her hair were brown and healthy". Never said long or short.
"Her face was pretty". That's it. Nothing more. I could describe the eyes. But that would be a pre-chewed food for the mind. That way the reader would see clearly what I had in mind. But that wasn't what I liked to happen on that part. I wanted the reader to imagine a brunette as he/she would personally define as "pretty face with brown healthy hair". The brain interpretation was doing half of the job. What I wanted to set up was there. A pretty face and brown healthy hair. The reader would define what is the form of a pretty face for his/her taste, not my taste. Sometimes less is more.
Never described hairstyle. The reader's mind will also do that. The reader will have space for his/her imagination to imagine that pretty face with brown hair. Imagination playing with the mind.
For instance imagine a brunette with a pretty face.
Imagine her beautiful face looking at you straight in the eyes.
There is a white curtain behind her.
Focus on her face.
Keep that face in your mind.
Memorize it!
You got that pretty face?
Tell you what.
Everyone saw a different face in their mind.
Now imagine this (pardon me English is not my native language, I will do my best):
Imagine:
A pretty woman.
Her brown healthy long hair, are tied as a ponytail.
The hair color shines at the white light that comes out of the roof lights of the Mall.
She has freckles at her cheeks and her thin nose.
What a pretty oval face she has. She is thin and slim.
Her thin lips, open revealing a white smile, while her almond shaped eyes show every expression of that smile around them, as her eyelashes fall to the level of your sight, trying to be as seductive as she can.
Her eyes are like an asian woman's eyes. Pretty. Grey colored.
But her skin color is more like Scandinavian white.
As you can understand I made a more specific recipe for interpretation.
Your minds can now imagine something more similar.
This is as pretty as it can be, according to this description.
Keep her face in your mind.
Which face was prettier?
Some might say the second.
But I suppose many will chose the first. Because it is near YOUR taste. Because YOUR brain formed it not mine.
Which face seems more friendly and familiar to you?
The second. Because you imagined it. Period.
Tell you what. The second description was also of a pretty woman.
But I like brunettes with a little Caucasian darker skin, brown eyes, and sexy juicy lips.
Some people like black skin sexy brunets.
I tried to make a description alienating everyone's taste, but still being pretty.
All those features merged together, should make maybe something not so pretty.
By defining she was pretty though, we merged all features and interpreted them inside a beauty framework.
So much description was not needed though.
The first example was enough.
A pretty face! BANG!
Healthy brown hair! BOOM!
Thus in my opinion, they know what they are doing.
The more interpretation there is, the better the game is for me.
I would LOVE to hear your opinions people.
This is a VERY interesting topic.
