The difference between our play-styles seems to involve how we frame the world. You seem to feel you frame the world as a series of disconnected events or places with creatures that the players may or may not engage. You seem to not mind creating that type of material continuously to create the illusion of a sandbox world where the PCs have more control over the direction of their imaginary lives.
I like to have a narrative the PCs follow where they participate in some grand story where there is a key antagonist they must defeat to save the world, kingdom, town, or whatever thing they are trying to save. I create scenes that are part of this narrative involving a variety of situations that lead to the defeat of this antagonist. The PCs world is generally limited to the scenes in the narrative rather than having the ability to move in a random direction of their choosing.
It is in essence the sandbox versus the railroad. I prefer the railroad and you prefer the sandbox. I feel a well-designed railroad can make for an interesting, exciting, and fun trip with a very satisfying and powerful ending that makes the PCs feel as though they accomplished something extraordinary in their lives ending as heroes of the land. All this talk of, "If I wanted a story, I would read a book or watch a movie" means nothing to me. My inspiration for playing this game is and has always been a desire to be a participant in the amazing stories I've read and seen, not wander around as some random person in a fantasy world. I wanted to be part of The Fellowship of the Ring. I wanted to go with Conan on his adventures. I wanted to be a knight in the Arthurian Tales serving Arthur and going on quests. My friends are similar to myself. I try to make them a part of extraordinary fantasy stories as protagonists that end up as the great heroes of their story. That's my preferred play-style.
I actually prefer a middle ground between the two.
I have "Squirrel!" syndrome. While saving the world from the tyrant, I enjoy finding a random crypt that has zero to do with the "campaign at large". As Lydia in Skyrim says "Hey, look, a cave. I wonder what's inside.".
The game feels more organic if there are random events, locations, and NPCs that have zero to do with the campaign du jour and more to do with the backdrop of an emulated living breathing world. There is no doubt that every DM at my table railroads the adventures to a certain degree, but as a player, I want to pick one of several options and I don't want all of the options to be steps into taking out this year's tyrant. Nothing wrong with being the hero, I just want the heroic deeds to be only part of the adventure, not the entire thing.
