YMMV: King's Quest: Mask of Eternity
- Awesome Music: No matter what you think of the game, you have to admit the main theme is awesome.
- Contested Sequel: Go to a Sierra fan board and ask if it's a King's Quest game. Then ask them if it's a good game. Make sure to bring chocolate, marshmallows, and graham (no pun intended) crackers for the inevitable cookout.
- Fanon Discontinuity: The fandom does not especially like this game. This game is largely ignored and/or derided by the fanbase as In Name Only, due to its drastic change in tone, reliance on violence in a series that usually rewarded you for thinking your way out of the situation, and protagonist that wasn't a member of the Daventry Royal Family.
- Good Bad Bugs: Scaling a wall with the rope and hook in the Underground Realm of the Gnomes could result in Connor ending up on the other side of the walls bordering the level. Weirdly, it wasn't just an empty wasteland - there were rocks lying around that could be picked up and zombies to fight.
- Irony: Despite this game is pretty much universally hated, this game is bundled with 7 on GOG.com. So if you want 7 (and have it easily work on modern computers) is to buy it with this game. The bundle was originally $9.99 but the price was slashed to $6.66
- Memetic Mutation: "'Tis beyond my reach!" Variations on this pop up in the Fan Remake of King's Quest II: Romancing The Throne and The Silver Lining. (Get lost, narrator. We're still debating if this is a King's Quest game or not.)
- Most Annoying Sound: The aforementioned "'Tis beyond my reach!" was an infuriatingly oft heard line.
- Vindicated by History: Reversed. Believe it or not, when the game first came out, it sold reasonably well, outselling Grim Fandango, and earned modest scores from gaming magazines, mostly around 70%. After Sierra went under and the adventure game market crashed, everyone turned on the game, now labeling it as the game that (temporarily) killed off the adventure game genre.
