[7] In addition, the game features some action sequences, quick-time events, and on-rail platform elements.

[13] He has only read about Daventry from travel guides he used to read as a child, and could not wait to see its famous landmarks for himself (the kingdom is reimagined as a bustling walled city surrounding Castle Daventry, where as in the original game the castle was a lonely keep, surrounded by mostly wilderness).

Classic games as well as The King's Quest Companion are reused for references and reimagined events including places from the expanded universe.

Chapter 1's prologue reimagines events from King's Quest I: Quest for the Crown and focuses on the Mirror of the three treasures as the main treasure Edward sent Graham on to become king of Daventry (as it had been the only treasure stolen from him), the events of the dragon's lair from the King's Quest I are completely reimagined as an action sequence involving being chased by the dragon, and having to make a final choice on how to distract the dragon to escape back up the well to the surface.

Surprising the royal family as they discuss vacation plans, they decide to allow Alexander to accompany them, and ultimately end up travelling to a mysterious Ice Labyrinth.

The princess whom the player did not choose turns out to be Icebella (reimagining some of the details from King's Quest V: Absence Makes the Heart Go Yonder).

Mordon ends dropping his "slave name", and changes his name to Mordack, further foreshadowing King's Quest V. Some of Alexander's dialogue also foreshadows events of King's Quest VI: Heir Today, Gone Tomorrow; he mentions that a crystal ball predicted that he would encounter a minotaur in a labyrinth in the future, and that he would encounter a woman with olive skin and green eyes.

The events of King's Quest V are revised, as well; rather than stonework, the location where Graham and Mordack had their magical duel had wooden floor boards, which he hid under after casting a fire spell.

The framing story takes place in the last weeks or months of Graham's life while he is bedridden from the poison in Chapter 5.

King Graham is relating the tales of his life to his grand-daughter, Gwendolyn, to assist her in becoming a wise and just ruler when he passes on.

Graham passes away later that night, leaving a letter for Gwendolyn to read that urges her to build her own legacy, rather than relying on his.

There were multiple attempts to reboot the franchise following 1998's King's Quest: Mask of Eternity, none of which went past the announcement or concept stages.

In August 2014, Activision revived the Sierra brand and had passed development responsibilities for a new game to The Odd Gentlemen.

[15] The script for the first chapter alone was 640 pages long, and included branching paths, Easter eggs, narration, object use and interaction, and dialogue trees.

[16] The game includes vocal performances by actors Christopher Lloyd, Wallace Shawn, Cherami Leigh, Tom Kenny, Josh Keaton, Maggie Elizabeth Jones, and Zelda Williams.

[17][18] The game was released in five parts in 2015 and 2016, with an optional playable Epilogue only included in King's Quest: The Complete Collection edition.

[32] Chandler Wood from PlayStation Lifestyle was pleased with this chapter this time around, giving the game 8/10, praising the "deep subjects of mortality, life accomplishments, and what we leave behind/Callbacks to King's Quest through the years/Conclusion that pulls the whole saga into context and finishes it out nicely" although being unhappy with the "sudden onset memory loss" and some "flawed" puzzle design.

Awards, the Academy of Interactive Arts & Sciences nominated King's Quest: The Complete Collection for "Adventure Game of the Year".
