Back in the Apple IIc days, I grew up on King’s Quest.
The last installment in the series (The Mask of Eternity) was about as far removed from the series as possible, and the likely culprit as to why the series died out. Of course, Sierra, became part of Vivendi, which became part of Activision. It seemed like the series was dead with no chance of revival.
While not an “official” game, this fan-made title, known as The Silver Lining, looks impressive with its attempt to recapture the “heart” of this fairy tale series:
It comes out for “free” on July 10. Not many fan-made projects get a break, but I think in the seven years that this game has been in development, it seems to been given enough immunity for Activision to politely look the other way in this instance.
