I agree for the most part, but keep in mind theres decent chunks of "writing" in video games that are mostly filler and probably no one would notice or can tell if the line is AI vs an intern who wrote it.

Like... npc one-liners and stuff like that, item descriptions, etc. Stuff where its probably not even gonna be looked at by 99.9% of ppl anyways and the bar for quality is very low.

Whats critical here us understanding that you dont replace your writers here.

You just took a boring/monotonous task off their plate so that they can focus time/energy on more important parts of the game
