It seems to me that anyone who has to have a fixed set of defining characteristics for the PC's personality has seriously missed the point of roleplaying.
Sure, I like the idea of Personality Traits and have used them in one form or another for a long, long time, but they are only a guide and I only really use them when I as a player am undecided about how the PC would react in a particular circumstance.
So, I know how Soltak Stormspear and Shergar Sunhoof will react because I know their personalities inside out.
So, I know that Soltak Stormspear hates Chaos with a vengeance and "Any Chaos is all Chaos" as far as he is concerned. He follows the letter of the law rather than the spirit of the law and is ironbound in his inflexibility towards those who break cult restrictions. He is also Illuminated and tends to turn a blind eye when doing things himself. He takes his Orlanth duties very seriously, including making the right challenges and performing certain tasks, but he is also an Uroxi and takes Chaos killing seriously. As an Issaries Associate, he tries to take the middle ground in most things except where Chaos and Traitors are concerned. He admires Trolls, being an Argarn Argar initiate, dislikes elves but respects powerful ones, he doesn't much care for dwarves. He dislikes most Beastmen, except Minotaurs, and hates all things Chaotic. He knows that when he dies, he is going to a Cloud Castle to become part of an Orlanthi Hero's Bodyguard and will be fighting Chaos for Eternity, so he is content in that. He was born a woman, Sabrina Spearsister, but was cursed to be a man on a cult mission. He has tried to change his appearance by taking on magical items and replacing his own body parts, this is partially to remove the image of the man he has become and partially to alienate himself from his fellows. He is married, to an Ulerian slave who he has technically forgotten to free, but he hardly spends any time with her anyway. He has an ambivalent attitude to women, he admires women adventurers as he wishes he was a woman again, but he is jealous of them for the same reason. For this reason, he has taken part in several forcings, both individually and in groups, mainly to show his superiority over the women, something he does not show any guilt over. Apart from that, he will protect the innocent as part of his Orlanth duties, but will not go overboard in doing so. He will kill dragonewts on sight, if possible, because he owns a set of Dragonewt Skin armour and has permanently killed the original owner, but doesn't want other dragonewts to find out. He hates Lunars as a point of principle and will always fight them wherever possible, with no quarter given or received.
Shergar Sunhoof is a Yelmalian Centaur Light Son, who originally talked of "My Uncle Ironhoof" before gaining the Geas "Speak only Truth to Everyone", so now he is silent about his uncle. He has the geas "Celibate During Fireseason" and makes up for it in the other seasons, being a bone fide sex maniac, seducer and rapist, he has no particular preference sexually, but draws the line at most chaos things and most undead, but sometimes the need overcomes such petty restrictions. His Bossman is Appollo, another Yelmalian Light Son, who he obeys pretty much without question. His crowning achievement was seducing Appollo on a HeroQuest, while he was under a Forget Enchantment, then casting a good Heal Body and Forget spell on him to cover things up, because he knew Appollo wouldn't really understand. Shergar hates Darkness Cultists, because Yelmalio has told him to, he challenges trolls to combat, not to chess or draughts or a nice game of cards like some Yelmalians, and normally tries to kill them. He has taken on the form of a demon in order to strike fear into his foes, so he has 5 legs, a Minotaur's Skull, wears a spider mask and has four golden hooves. He despises Dara Happans and fights them whenever possible. He thinks that Praxian Sun County types are wimps and has joined Appollo on several expeditions to kill them. He admires trolls, although he has to hate them, he quite likes elves and humans, but centaurs are the master race, especially easily caught mares. He has a herd of centaurs as a personal Heroband, of which he is the Stallion King and he takes his duties very seriously indeed. They form the basis of the congregation for Appollo's Temple. He's not keen on Chaos as Chaos has tried to kill him before. He particularly hates Vampires and Thanatari.
Clearly there is a lot about them that I haven't described, but none of those came from Personality Traits. In fact, I designed their Personality Traits based around their characters and life experience, just so I could explain them to others. But, I could play them now almost as well as I played them 15 years ago when I stopped playing RQ and started GMing.
So, character traits etc are useful tools in describing a PC to others, but should not be the be all and end all of things. If you need the Character Traits to play a PC then you are really missing the point.
All in My Opinion, of course.
