Should Microsoft show what Master Chief looks like? If anyone says no then you can't really explain why Tali's face should be shown.
There is a difference. Master Chief is a blank slate "insertyourselfhere" protagonist.
Tali is a fully developed character which you do not control, but interact with.
Master Chief should never be shown because he's a power fantasy for thousands of people around the globe. He represents humanities best and showing what he looks like would be viewed as a statement.
The Chief is more of a walking symbol then a character. As with "V", there
is no face under there.
Tali on the other hand is an interesting, young, kind and flawed character.
I went into more detail in my above post, but seeing her face is needed for the emotional climax of her character. It could be used to say something about her, as with the Darth Vader example.
