Grand Theft Auto has a funny way of portraying a variety of females. From the run of the mill obese America to the slutty, bad decision making teenager, realistically at that. Who was Niko's love interest, a girl named Kate who was both mediocre in attractiveness and actually developed positive/negative opinions on you depending on your greed?
GTA V is a bit worse though, what with the dating of silly strippers and what not.
And I don't quite agree with Assassin's Creed's portrayal of women, and men for that matter. Some of their historical paintings show them to be rather uh...unattractive. Except Anne Bonny, who actually looked like a sex symbol in most of her paintings.
