That's a shame. The "pref" is whatever the user has set on their device, and I wish more sites would respect that, rather than defaulting to their own "pref".
The whole thing is automatically generated? Does anything persist? If I could be in the middle of reading it, and the next day it's completely different, that's a huge waste of my time.
I've run numerous interactive text adventures through ChatGPT as well, and while it's great at coming up with scenarios and taking the story in surprising directions, it sucks at maintaining a coherent narrative. The stories are fraught with continuity errors. What time of day it is seems to be decided at random, and it frequently forgets things I did or items picked up previously that are important. It also needs to be constantly reminded of rules that I gave it in the initial prompt. Basically, stuff that the article refers to as "maintaining state."
I've become wary of trusting it with any task that takes more than 5-10 prompts to achieve. The more I need to prompt it, the more frequently it hallucinates.
