I was under the impression that the breast size would be enforced, not for the sake of male gaze, but for the sake of being average and not on the extreme end.
But yeah, I can't take such an idea seriously and I'm pretty sure it wasn't meant to

Also, to further highlight how women are portrayed in video games and the male gaze.
If a male character is ugly, old, has a nasty scar, overweight, has a burnt face, then he has personality, he's interesting, unique, cool, morbid, scary, dark, etc.
If a woman displays any of those traits she's simply unattractive and nothing more.
