Dingo Pictures' King's Quest VII: Generic Princess in Trouble.
This game was so fucking expensive it basically killed Sierra On-line; they lost over million in fiscal years 1993-94 because of the money they were pouring into this monstrosity.
After nobody liked it, the Williams sold to CUC and retired to their new lives of making frowny faces whenever OldManMurray made fun of them.
It's been many years, but watching this triggers the incredible embarrassment I felt wash over me when I started this up for the first time with a dubious friend at my side. His opinion: "Gay, worse than Dragon's Lair."
MYST, here. I was looking forward to this piece of shit, because I actually got Sierra's stupid self-published monthly fan magazine which of course made it sound like the second coming of amazingly awesome, and then when it actually did come out I heard nothing good about it.
