"But that flatness bothered me enough."

Current Events

I don't like modifying existing characters to mute their attractiveness. But are they seriously trying to say that every woman needs Sir Mix-a-Lot's approval?

This is an attractive model and they're letting her be attractive. This isn't like Mass Effect hiring an attractive woman, then uglying up the character in the name of virtue signaling. This is letting an attractive woman be who she is.

Judging from the attire and weapon, I kinda get the feeling that she has more going on than, "Does this make my ass look flat?"

Whether you're looking at hambeasts or bodies made for sex, there shouldn't be a one-size-fits-all approach. There should be no uniform standard for how to design female characters in a video game. Enjoy your AI still photo. This one didn't need it.
