You're probably right that the terrible writing is intrinsic. However, there's always been kind of a core team, since even the Witch Trainer 1.6 days, and without going through forum posts it's hard to say who had what responsibilities. Everything, from job descriptions to polls about how to decorate links, is always couched in the same stupid purple prose as you find in the game.What I am trying to point out is this: the core of the game, the really, Really shitty writing, is clearly being done by the main person behind this whole project.
I know Khan has been around since the team's beginning. I had the impression early on that he was the coder, and one of the other guys was doing the writing. But maybe he was always a writer who only coded grudgingly, and now coding has primarily passed onto "Boatswain Andy". Now if I could just figure what a "navigator" does with respect to game dev, and what a "quartermeister" even is, I might be able to speculate how likely it is the head writer could depart without taking down the whole project.
