Well, you don't really create Shepard in Mass Effect. More like direct. Unless you mean the face you made for her/him... Which I obviously liked, but I was attempting to make one that is believeable for a badass leader and war veteran than some fantasy girlfriend.
She still has an attractive face, but I'm usually rather judging how well I managed to put that toughness in there than thinking about how hot she looks.
I admit that one of my female Fallout 3 characters was made to be as hot as possible. She still looked pretty awesome with (mod added) long blonde hair, eyepatch and yellow eyes. Not too believable (especially in that setting) or warrior-like. Minus eyepatch... Which I think I added exactly for the contrast. Now that I think of it, yellow eyes worked like that too. But that's what I liked about her looks - She kicked everyone's ass despite looking like a jackpot for raiders.
Then again, you never really get to give any personality to your characters in that game, so how they look becomes more important.
