I think the staleness comes from the fact that it’s the 60 billionth time you’ve done some “quest” to go gather some crap up or kill the same thing in a loop for an hour.

No amount of dialogue is going to save that.

The actual story dialogue is usually interesting enough already

Nah, they’ll still be stale. Many people play RPGs that haven’t changed in 30 years, so static isn’t an issue either.

And many people don’t, there are already skyrim mods for this so your point doesnt really hold water.

It’s so funny to reference a game that has like 12 editions and is on every platform including a refrigerator and think “this game is missing something”

By the way there are LLM dialog mods for Skyrim and everyone thinks they’re a joke because they suck.

you seem to enjoy speaking in absolutes, that's a really bad habit

However, no one has ever praised the Elder Scrolls storyline.

They win by the sheer quantity and by giving you a lot of subsystems to play with.

So LLM generated quest text probably feels it belongs here. It wouldn't, for example, in something with the Witcher 3 story quality.

except the hundreds of hours of youtube videos discussing the story of the franchise

Quality writing is what is most important in an RPG, something that LLMs are distinctly terrible at.
