In a more serious response to the question, especially in the vein of beautiful women in Bioware games, I think it may be a larger question to ponder. I should preface this to say that I am, as a general rule, against the circus pagent around romances and that type of content in Bioware games and would advise Bioware to get out of the practice if at all possible. That being said, read below.
DA:I has seen some complaints about its lack of "hot" LI options for straight male players. While I personally don't find Cassandra or Jospehine particularly ugly, it was a stated, intentional move by the artist team to create the look of the characters to complement and convey their characters. Cassandra was drawn with hard facial bone lines, instead of softer angular ones, to show And emphasize her hardened personality. Similar attempts to use physical deviations were done with Josephine, including a slightly crook nose and a bit of an overbite, which help to convey less of a super-model type figure and one which may actually be realistically stunned that the Inquisitor really WAS flirting and hitting on her during their romance. Sera was also made to look somewhat impish, with a flat nose, boxish face and often sour demeanor and tone to match her usually chaotic behavior.
This tactic, to use small physical flaws to help build the character rather than more streamlined, symmetrical, Golden Ratio beauty, is an interesting one. However, given some of the complaints, I feel like it was not executed like it should have been.
1) This treatment was not applied across the board.
Morrigan and Leliana look like 20 year old super models, despite being over a decade older and possibly having kids. Yet other female characters are given quirks and defects in an attempt at realism and character depth. Similarly, Cullen actually is the best looking he's been so far in the series (from an objective straight male's perspective I suppose), while Dorian is a mustached Kal Drago. Even Viviene, romanceable by no one, is given the appearance of a classical beauty (minus the shaved head, of course).
If all characters were given quirky noses or somewhat effeminate jaw lines or teeth that didn't appear as if there was the equivalent of Thedosian magical orthodontists, this may have been less of a clash. But instead, the player is given classically beautiful Inqiisition members, but is only allows to pursue the less-classically beautiful ones.
However, I think it is more than that. Which leads us into...
2. The Technology Isn't There
This is where I think the issue lies.
The Uncanny Valley, the area where graphical realism is approached so closely that it actually looks WORSE by comparison to real life, is a constant struggle in video game development. Making characters look real and alive, instead of life-like puppets on strings, is a very difficult task.
Looking at the characters of Inqisition, one cannot argue that they are very realistically rendered, with the best modeling in the series thanks to the Frostbite engine. However, when rendering characters that are either super-model beautiful or who are generic NPCs, the difficulty may be different (and, indeed, HIGHER) than trying to combine elements of the two. Creating a character who conforms to our ideals of traditional beauty, while also making "disposable" NPCs who are forgettable and unremarkable, may be more of a straightforward task than taking someone who would be otherwise traditionally beautiful and introducing mundane quirks.
It could be that just as computer artists struggled to capture traditional beauty in video game form (with many failures - pyramid boob Lara Croft from PS1 days, I'm looking at you), maybe there is a struggle now to capture slight imperfections and faults in a way that makes them endearing and cute and that doesn't, instead, make them look marred and non-attractive. If that is the case, then these flawed beautiful characters may actually be more repulsive than the standard, nearly-faceless NPCs. Because the challenge is to create beauty that is able to cross the Uncanny Valley, but then make it more realistic by including natural, everyday imperfections, these attempts may actually slide the effect of the character's appearance right back into the unnatural realm of appearance, making otherwise normal features appear to be grossly apparent.
Just a thought.
