Try again. It's really that good. Especially in "custom scenario" mode (option 6, then arbitrary prompt). It seems to work particularly well if you switch the input to Story, and start describing the narrative (instead of what you say or do). Some spectacularly good results come from leaving sentences unfinished, for the game to complete.

The most mind-blowing scenario I got recently started with this prompt:

$ You are Ted, a holodeck technician. You test this AI-generated world in order to determine its limits. You start the simulation with a program of a beautiful beach. As you enter the holodeck,

...

I don't want to spam the comment with too many examples, but I must say that my mind was completely blown. With zero hinting, the game was able to pick up on the interaction styles like ($ denotes what I write, > denotes the reply):

$ You ask, "Computer, create an anvil 5 meters in front of me and 10 meters up in the air."

> You see an anvil fall from a great height in front of you and land on the ground, mere centimeters from your foot. To test the limitations of the program, you try to move the anvil. You are surprised to find that it is fixed in place; you cannot move it at all.

$ You say "Computer, what is the mass of the anvil in front of me?"

> The computer responds: "The anvil has a mass of 555.9 kilograms."

$ You say "Reduce its mass to 10 kilograms."

> The computer responds: "I'm sorry. The mass of the anvil cannot be changed."

$ You say "Explain why the mass of the anvil cannot be changed?"

> The computer responds: "The laws of physics in this program are pre-set. I cannot alter them." You note that as a software bug.

...

After which the game started coaxing me towards a mystery story on a holodeck and tried to suffocate my character through safety failures. I tried the lamest way out:

$ In desperation, you tap your commbadge to initialize emergency beamout. You pass out.

... which worked. The game generated a realistic story about my character's hospitalization - while keeping the Star Trek setting - and then a page of text later, it pushed a narrative where the character gets kidnapped by alien robots and later dies in a shootout with Andorians (which the game introduced by itself, out of the blue, but in a way consistent with the story).

Point being, its training database is good enough to pick on a franchise in which you do your world building, and can sometimes keep the context for longer than you remember it yourself. And even when it confuses locations or people a bit, it often isn't that jarring. To me, the transitions feel like how my mind does it in a dream.
