As a Quarian, Tali wears a protective suit covering her entire body. This also means that if you did choose to embark in a relationship with Tali, seeing her face, free of obstruction should be a very powerful moment in the narrative. While you were unable to view her visage unencumbered in the first two iterations of the game, Bioware promised that in Mass Effect 3 you would get that magical moment of clarity.
It turns out this magical moment does happen, although you only receive a digitized image not a full rendered animation of your possible galactic love. Gamers unhappy with this conclusion on the Bioware Social Network scoured the internet and the found the EXACT same image in a free stock photo collection available online. Although the image in-game has some very small adaptations it is a near copy.This oversight has caused a huge amount of uproar within the gaming community as gamers try to understand why such an important moment was left to something so arbitrary. So far there has been no response for Bioware.
