My dream is for King's Quest to become a world unto itself, like Dungeons & Dragons is. Many stories, many families, many kingdoms, worlds and adventures to explore. I think "King's Quest", the universe, can go beyond the Royal Family of Daventry.
Look at Adventure in Serenia--That sort of idea. It's the same universe, indeed, same land as KQ5, just different characters with no direct connection to King's Quest.
I would LOVE that. That was part of my idea behind the King's Quest roleplaying thread on these forums, but not enough people seemed interested.
Honestly, I'm a BIG fan of MoE as a game and even as a game set in the King's Quest world but I felt that -- like Adventure in Serenia -- it needed to be a bit more separated. You could honestly make games set in the KQ world in SO many genres -- simulation (a medieval Sims game that takes place in Daventry?), strategy (kingdoms warring against each other -- not Daventry, cause hello Shield, but maybe like... Eastern & Western Kolyma, etc), adventure (been there

), action/RPG (a la MoE)... you get the idea! Not to mention tabletop RPGs!
There is so much that can be done with the universe of King's Quest. All it takes is imagination.
I'm going to take this moment to not-so-subtly shamelessly plug some things to help encourage this sort of creativity....
First of all:
King's Quest Roleplaying Thread! Check my signature or click that link!!

Second of all:
Creative Expression section of the forum -- perfect for writing out your ideas for the KQ universe!
Thirdly: King's Quest Omnipedia -- did you know it has a
fan fiction section? And, were a successful roleplay to begin, I bet Baggins would agree to let the RP be archived in the fanfiction section!
Fourthly: My much less specific and still fledgling
Arcane Lore Wiki for all things high fantasy -- including King's Quest! It's meant to be a very lore-specific resource for writer's and RPers. (Much like the all-inclusive
SciFi Wiki... but, y'know, less science!) I'd love to have some fanfics and RPs to archive and/or link to on there as well!
And.... as a source of inspiration, the
Encyclopedia Mythica pretty much covers all the mythology and folklore you could ever want.
SO... my challenge to all of you.... Let the creativity begin!
...and if it helps, I'm also going to post the Prologue to the fanfic I'm working on this weekend. You have been warned!
