Accidental Aesop: During the series, the Hero can order alcohol drinks. Abuse too much of it and you'll end-up either dead or de-possessed of your money.
Awesome Music: The series as a whole generally has memorable music, but a few tracks ascend to Awesome levels, particularlyinQFG4. There's also the 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 a certain lovely wizard's garden spot...
Complete Monster: Ad Avis, the Big Bad of the second game, is a cruel, misogynistic wizard who takes over the city of Raseir, where he turns it into a hellhole where slavery is permitted, women are forced into harems and treated as dogs while Ad Avis slowly drains all the magical life force in the city. Seemingly defeated, Ad Avis returns in the fourth game, where he is turned into a vampire by his mentor Katrina and intends to summon a monstrous Eldritch Abomination to plunge the world into eternal night and chaos. Betraying Katrina, Ad Avis also intends to torture The Hero to death while trying to bring about the apocalypse to satisfy his own ego.
Fan Nickname: Devon Aidendale for the Hero, the name given in the prose-style writeup for the official strategy guide.
Game-Breaker: The Paladin class as a whole. In Quest for Glory III, once the Paladin earns the "Heal" ability he's granted the Magic skill. By Quest for Glory V 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 Fighter/Wizard, but he also carries the best sword in the game, and has his own class abilities on top of that!
Goddamned Bats: Badders in QFG4. Baddies and Humunculi in QFG5.
Good Bad Bugs: Even though the Paladin isn't supposed to have magic, because the games treat his abilities as spells — except Paladin abilities use the Honor skill as their modifier, rather than Magic and Intelligence — he's able to unlock almost every spell in the series. As noted above, this makes him a serious Game-Breaker, as he not only gains all the advantages of the Fighter and Wizard, but none of their weaknesses, and has his own unique abilities, on top of the best sword in the franchise.
