I always Roleplay my characters' physical appearance according to their lifestyle. My Roegadyn here will be brutish, scarred and visibly aged (as befits someone close to the fifties who has worked at a forge for a lifetime, or battled wielding axes).
In  WoW my rogue was an old military veteran who was pretty ugly due to a lifetime of scars (most done by player characters, as far as having half his face burnt).
My SWTOR bounty hunter was similarly ugly.
My Secret World mage character was a sickly, gaunt sort of Lovecraft type.
I do RP extremes, but I think that these quirks and choices add a lot of flavor, but then again I am one more prone to have characters with a much wider set of flaws than actual prowess in any field, because I think that it's limitations, and not masteries, which bring greater depth to interaction. Most my characters excell in one of three areas: Social interaction, physical strength, or mental strength, and then are 'neutral/secondary' in another, and 'bad' in another, as a rough picture.
