(re: KQ4 AGI)
That secret code was part of a sweepstakes. A trip to the UK, if I remember correctly. When you won the game, you could write the code down on an entry card and send it in to Sierra to be entered in a drawing. Whether or not anyone won, I don’t know. As far as I know, this was only part of the first SCI version. The one I have on my KQ Collection doesn’t have a code, while my original disk version does. Anyone know if there are more than two SCI versions out there? Even between the two I have, there’s a slight graphics difference (not in quality, just detail).
