Hmm, ok I think Annette Childs got the story credits in KQ2/3, at least the manuals, I think. Roberta got the "designer" credits.
Hmm, while Roberta is listed as the third billing in the intro credits as designer, director and producer, I just looked at the ending credits for KQV, strangely Roberta Williams isn't even listed (except under a couple of voice credits), William D. Skirvin got the top billing as Creative Consultant. Although she is listed in the "About KQV" tab, "King's Quest V...By Roberta Williams". She isn't listed in the main credits for KQ1 SCI either for whatever odd reason (but shows up in the "About KQ1" credits.).
If that sort of arrangement had indeed happened, it would have been potentially disasterous to the franchise, as whoever ended up purchasing the license could do whatever they wanted to do and Sierra would not have had the ability to stop them. Let's take, for example, if Peter Spears decided to write an entry into the King's Quest Companion a little blip about Daventry being some kind of space pod experiment that Manannon and Mordack cooked up so they could play God.
Well, let's see through all the editions, he pretty much states that Roberta Williams games are just games, and not the real story (his/Derek's version is the "real story"). What about the part in KQ7, 4th edition where Derek Karlavaegen implies that KQ7 didnt' happen, and was all just a hoax? He also took the creative choice to say that the remake of KQ1 was not the real story, but the original version was. Although evidence from later Roberta Williams interviews seem to say she considered the remake to be the story she wanted to tell. It was placed in the classic KQ1 boxes and replaced the older version until the release of the anniversery collections (its also the version Sierra's owners later replaced previous versions with in the most recent collections). This largely has an effect on the order of how the treasures were found. There are also some major differences between items and certain aspects of the KQ6 story (but that was more to do with them working from a prototype version of the KQ6 script, and not all the ideas had been finalized). For example the face on the copper coin was Valanice instead of Graham, the drink me bottle was empty (and Alexander acted his death, and Hakim acted along with him), rather than it being filled with something that would knock you out, and make it look as if your heart had completely stopped (tricking Hakim as well as Shamir), among other things.
There are also a few examples in the first two editions where he actually changed character names, or made them less clear. For example, Jym and Tam Baker, the baker brothers of Serenia, no reference to William Baker. We are made to believe that the guy working on the wagon in town was one of the brothers (this example is in the Second Edition. An Encyclopedia of Daventry, a section left out in the later editions). He also made Manannan's cat female, when he was clearly male in the game (or alexander isn't able to tell the sex of cats very well, :p). Although it may have been a previous cat of Manannan's (since it was from an article, "Fragments of the Sorcerery of Old" by an Unknown Author).
Its worse in the Space Quest Companion, where he changed the names of a number of the minor characters or organizations to give them names that followed his sense of humor. For example the Gippezoid Novelty Company was replaced with the Patrician Broadcasting Company, or PBC (a play PBS, Public Broadcasting System). The merchant of Venus, Nelo Jones was given the name Ronko ProPeeler a pun on Ron Popeil, of Ronco fame. The Employee of the Week, is female, when in the game he is male (and gets mad if you assume he is female, this may be part of the joke, since its from Roger's perspective). Fester Blatz's race and heritage is a bit different. He's a 'Hermanoid' rather than a Phleebhutinski, and is apparently not the last of his species. There are apparently plenty of Hermanoids around the galaxy.
If we looked at the novels, King Graham, has blond hair in Kingdom of Sorrow, hah hah (not counting the cover artwork, where its black). The kingdom was pretty peaceful, about 2 years before KQ3, with no sign of the Kingdom's impending doom from the dragon heh heh. The timing of The Floating Castle which covers a time frame of about a year, may not easily fit between KQ4 and KQ5 (since official timelines don't leave much room in that timeframe, less than a year at the most), and certainly not after KQ5. We are also told that Alexander was 18 when he escaped Mannan, rather than 17. We are also told that the kingdom was in possession of the magic mirror for about 200 years (rather than the 500 in KQ1 manual). There is a sentence in Kingdom of Sorrow that would seem to imply that Alexander and Rosella aren't twins. He muses that his son would be about the same age as William if he were around (who had just turned 10), his daughter was seven at the time. Granted 7 is about 10, but its not the best way to word things.
As for the whole licensing thing, I am quite sure that Sierra didn't just sell the licensing rights to Peter Spears (or whoever) for them to do as they pleased. Not when dealing with their flagship franchise. Business does not and has never worked in that fashion... ever. I would really like to see those quotes you mention from Ken Williams saying that Sierra sold the licensing rights to King's Quest novellas and the like and didn't maintain creative control over the whole thing.
Here is that quote you wanted to see;
Sierra had nothing to do with the Kings Quest novels, beyond licensing a company the permission to write them. I asked Roberta if she read them, and she says she thinks she did, and that she thought they were ok, not great.
-Ken W, Sierra Gamers 12/8/2003
Ok lets look at other licensed products, Quest for Glory Authorized Guide, and one of the designer's thoughts on the book;
And by the way, mentions of "Devon Aidendale" and Willowsby (or Willowdale or whatever the name was) drive me crazy. Devon was just the name Paula Spiese chose for her QG hero, and she used him in the strategy guide she co-wrote with Lori. Those names have no "official place in the canon", except of course they've been enshrined on Wikipedia because they're part of a published book." "We did not name the hero, nor his starting village, for a reason. We wanted every player to imagine their own hero's background so that the player would really become a part of the story. So it's frustrating when I see other people adopt Paula's fantasy as their own. Still, if that makes the game more fun for you, go with it!"-Corey Cole
So ya, Sierra did offer its licensing out without retaining complete control in some cases. Even some of the material published in-house was not necessarily completely under Roberta or other designers control. For example all evidence points to the King's Questions being put together by another team other than Roberta Williams from what I've been able to dig up. I don't think she had anything to do with Hoyle Book of Games series (and Graham's Board Game Challenge) either. She always maintained aspects of her story that were alternative to aspects of the King's Quest Companion that were published as well in other published sources. Such as the cosmology of Daventry (in our world vs. another?). I once even asked her during a fan chat back for the release of MOE, about the world, and she even said it happend along time ago in our past (parroting what we have been told in the manuals for most of the series, the KQ6 introduction, and most of the articles she has written).
Seriously instead of speculating who and what was behind the King's Quest Companions and how much "licensing" deal was going on, read the Acknowledgement pages, he spells it out pretty clearly, and what went on with the designer process for his books. Peter Spear wrote as I recall (this was third edition version) mostly acknowledges having talked to Ken Williams (not Roberta Directly) and Jane Jensen, and other assorted Sierra employees. He does thank Roberta for creating the universe though. About the only quote we have on Roberta's opinion of the books (concerning the his version of the universe) is on the cover of the Third Edition (though there was a different review from her on a later reprint of the first edition).
The King's Quest Companion is an interesting blend of fiction and helpful information for playing my games. Anyone interested in reading the story behind King's Quest or who just needs to be 'unstuck' while playing the game will find this book invaluable."-1st edition."
"...wonderful blend of fact and fiction that brings my games to life in an exciting, new way. It adds another fascinating dimension to the entire King's Quest experience. It truly is a pleasure to read and a must have for anyone hoping to explore the series in greater depth and detail.-Roberta Williams, 3rd and 4th edition cover
The explanations for Hagatha/Mordack/Manannan primarily appears in the second edition in the An Encyclopedia of Daventry, and a single refrence in the KQV novel that isn't really explained within the story (the latter was reprinted in the 3rd/4th edition). I don't think he ever connected Manannan and Hagatha together in the first edition at all (I think both were treated as separate villains).
That being said, the internal aspects of the games or the manuals weren't always consistent. Setting alternate dates for many of the events, the age of Alexander in KQ3. Was he 17 turning on 18, or 18 (possibly turning on 19), or even 19/20.
