* CrowningMusicOfAwesome: The series as a whole generally has memorable music, but a few tracks ascend to Awesome levels, [[http://www.youtube.com/watch?v=uaKj8VQ7ePs particularly]] [[http://www.youtube.com/watch?v=V13HEisneF4 in]] [[http://www.youtube.com/watch?v=dCMtUQbe1HQ QFG4]]. There's also the [[http://www.youtube.com/watch?v=H0GhLzOVRkQ titular theme song]], but the most famous song of the entire series (and quite possibly that entire era of adventure games) actually comes from the first game, played in [[http://www.youtube.com/watch?v=JDUrQSIRgOo a certain lovely wizard's garden spot...]]
-->'''Katrina''': "I bet you say that to every girl who chains you up and has a whip."
* GameBreaker: The Paladin class as a whole. In ''QuestForGloryIII'', once the Paladin earns the "Heal" ability he's granted the Magic skill. By ''QuestForGloryV'' the Paladin can learn ''every'' spell in the series, except for the handful of that specifically require being the Wizard class to learn (most of which are plot-specific). The Paladin is therefore not only a hybrid [[MagicKnight Fighter/Wizard]], but he ''also'' carries the best sword in the game, ''and'' has his own class abilities on top of that!
* GoddamnedBats: Badders in [=QFG4=]. Baddies and Humunculi in [=QFG5=].
* FanNickname: Often thought to be averted, since the name of the main character is known, among many fans, as Devon Aidendale, a name taken from a strategy guide. WordOfGod says it was just the name of that writer's character and insisted that the hero is supposed to be whoever you want them to be.
* ShipToShipCombat: Between fans of the Hero/[[FemmeFatale Katrina]] and the Hero/[[SealedGoodInACan Erana]] in QuestForGloryIV. Then came QuestForGloryV and two more ships came between the Hero/[[LadyOfWar Elsa]] and the Hero/[[HelloNurse Nawar]].
* WhatCouldHaveBeen: The Coles have [[WordOfGod said on record]] that several intended features had to be cut from the series for various reasons, usually time and technical limitations. For example, the first game was supposed to have different races (Gnome thief, Elf wizard, Centaur archer, Human jack-of-all-trades) and a large Goblin warren maze; the former was replaced with the three classes, while the Goblin base remains as TheArtifact of the latter. Similarly, the fifth game lost the ability to use bow and arrow, and to play as Elsa, over the course of its development.
** Other artifacts of the first game: The workshop appeared to be occupied in the original version of the first game (the remake made it more clear that it serves no purpose); it, along with the butcher shop, barber shop, and bakery were probably intended to serve some sort of purpose that was scrapped, and thus are always closed in the final version.
** The second game, ''Trial by Fire'', was meant to be a 256-color VGA game, which would have made it Sierra's first, until [[ExecutiveMeddling Ken Williams decided to reserve the honor]] for their latest flagship game, ''VideoGame/KingsQuestV''. As a result, Trial was relegated to EGA status.
* WordOfGod: The series was originally intended to be four games, but in the design process for ''Shadows of Darkness'' the Coles decided that going from an evil wizard to an EldritchAbomination was too far a jump for the BigBad, and made ''Wages of War'' as a transition. In a 2008 interview, they added that after completing ''Trial by Fire'', they felt that Rakeesh and Uhura were "crying out to have their stories told".
** Additionally, the Coles have said that Glorianna, the games' setting, is an alternate Earth which suffered an explosion of magic, creating the various animaloid races like Liontaurs, as well as making time flow differently in different parts of the world (hence the SchizoTech).
