I figured I'd visit a game series I particularly love (but still moan about quite a lot): "Fable". "Fable", when it was first released, was one of the first games to really explore the depths of in-game AI and the troubling matter of cause and effect in the gaming universe. Additionally, to my recollection (and incorrect it may well be - I am open to corrections on this), it was also one of the first that allowed quite a high degree of detailed customisation, in terms of costume, hair, weapons, etc.
The first game in the "Fable" series, although highly customisable, didn't actually allow the player to choose a female character. Hero, the character's default name was always a young boy, and as he grew into a man, you could define his character as finely as you liked. Clothes, hair styles, even tattoos were readily available to buy in game and apply. In addition to the conscious aesthetic choices provided throughout the game, your actions also affected ultimately how your character looked. You start off with a "normal" looking guy - sort of thin, short, mousy hair. Dependent on whether your actions were regarded as good or evil also contributed to the way your character looked. It worked on a sort of sliding scale, i.e. +100 was totally Good, and -100 was totally Evil. +100 meant you got gradually blonder, blue marks appeared all over your body and you got a literal halo. -100 meant you got gradually darker, more frowny, reddish marks appeared all over your body and you ended up having two horns coming out of your head. So, in theory, the more evil you are the more likely you are to develop hideous malformed growths on your face.
