Trivia: King's Quest
- Cash Cow Franchise: At least until the bottom fell out of the adventure game market in the mid-late '90s, taking Sierra with it. It typically got first dibs on any new technology as a result, which could be either a blessing or a curse depending on the game.
- Fan Nickname: Among fans, the games are almost exclusively referred to as "KQ [roman numeral/#]"
- The Other Darrin: Each member of the Royal House of Daventry has had at least more than one voice actor. Graham (Josh Mandel in KQV, KQVI, and the AGI fan remakes, Danny Delk in unused audio from KQVII, Daran Norris in Mask of Eternity, Christopher Lloyd and Josh Keaton in A Knight To Remember), Alexander (Barry T. Smith in KQV, Robby Benson in KQVI), Valanice (Sheryl Bernstein in KQVI, Carol Bach y Rita in KQVII, Kath Soucie in A Knight To Remember), and Rosella (Diana Wilson in KQV, Bernstein in KQVI, Maureen McVerry in KQVII). Cassima can also count as a new member of Graham's family, since she is voiced by Dianah Pressley in KQV, and Louise "Stevie" Vallance in KQVI.
- What Could Have Been:
- Sierra was planning remakes for the rest of the early King's Quest games, but the negative reaction from the fanbase to the King's Quest I remake caused them to reconsider. That didn't stop them from doing remakes of other first installments of their popular series, including Space Quest and Leisure Suit Larry.
- Telltale Games at one point was attached to the franchise, planning on an episodic Revival, but rights complications prevented it from happening. Despite this, the 2015 entry is episodic as well.
The books provide examples of:
- Approval of God: At times the official canon makes references to material from the books, in manuals and hintbooks, some of the King's Quest Collections, the King's Quest trivia game "King's Questions", and Sierra's Interaction Magazine. The manual for KQ6 even utilizes Derek Karlavaegen as the author of that manual. Roberta Williams has also endorsed The Silver Lining and A Knight To Remember.
