I don't know that better writers would change much really. I have no doubt everyone working on writing and scenario building within Bethesda is fully competent and capable and talented. The more likely culprit for how the writing can wind up being kind of poor is the inevitable consequences of needing to make the game open-ended and free form while also accessible to the largest amount of people while also 'safe' around certain topics while also working within a greater organizational hierarchy(read: writers likely don't have as much pull as they should). So even the best ideas will wind up getting squashed a bit and end up stilted or incomplete feeling. Meanwhile, plenty of dialogue winds up in that "You can write this shit, but you can't say it" awkwardness because it has to be neutral and flexible for the open-world engagement.

That's my hunch at least. Because there are certainly examples of good writing throughout Fallout 4, but they tend to be in the more tightly managed scenarios. The USS Constitution quest was a pretty tightly run small scenario that I thought was conceived and executed perfectly well. A lot of the stuff thrown into terminals has been great and incidental dialogue that doesn't affect much tends to be solid.

Would that I could change anything I'd wish for Bethesda to have a "It's ready when it's done" shipping mentality instead of hard deadlines and I'd give the writers more creative control in general to shape the game's scenarios.

Bethesda fell into a bit of a trap with Skyrim where they thought they could, at no small effort, build an engine that effectively created a game in real time dynamically, which is a great accomplishment but arguably we're just not really 'there yet' and where something like that should have been lightly augmenting bold storytelling, too often it went hand-in-hand with the story, thinning out both elements along the way. Fallout 4, I've found, implements radiant stuff better than Skyrim, but it still feels like it's coming at the expense of, rather than in complement to, real storytelling.

It reminds me of George Lucas and the SW prequels a bit. He was so eager to jump to making movies with computers and he wasn't exactly wrong to do so but he did probably try to do too much too fast vs. say Lord of the Rings, which better showed restraint to use its CGI more responsibly while telling a great story.

Rambling now, but those are my two quarters.
