its amazing how people come up with worlds in their heads
its a true beauty that language has evolved to be able to communicate entire complexities that represent what is years of thinking
i know people dont like it in books because often the story falls flat
one of the first prominent worldbuilders is Tolkein and his impact is synonymous with fantasy
compare with C. S. Lewis who also was one but his method involved story first and then a world justifying it
i think without capitalism and copyright laws we will see a lot of collaborative works that build a world in fiction
think of franchise owned "extended universes" or roleplaying game worlds
you see this emerging online a bit with online roleplaying fiction and open universes like the SCP Foundation
scp is such good horror probably because of its collaborative nature. there is so much depth to the world that it becomes a horrifying place, knowing that there are unexplainable and dangerous things hidden everywhere not even new world order has a chance to scratch the surface. no one individual could create a universe so large.
