>As a clear obvious example: interactive fiction / text-adventures use a deterministic natural language interface with low load as an intentional flexible puzzle to solve.
Even though games can technically do this, should they? Do consumers actually find it fun and engaging? Considering there has never been a AAA game of that genre I don't think there is true consumer demand for games with such an interface.
If you think the Infocom games were like Zork I-III you don't understand how the ZMachine itself was improved over the years upon creating masterpieces such as Trinity or A Mind Forever Voyaging.
Then Curses!/Jigsaw are something else, and Anchorhead/Spider and Web/Inside Woman/All Things Devour are the king of games with thematics you won't see in 3D AAA games in decades.
And over the years the parser from Zork was so improved that could do chained phrases in English in the 90's on a 16 bit machine with the Z5 version of the Z-Machine with games designed for it. For Z8 machine games, the size of the games was even higher with far more objects and interactivity for puzzles thanks to Inform6 and Inform6lib depending on the build target.
I played Spanish IF games too from the ZX, but emulated, with PAWS (the adv system) adapted into Spanish. As the English grammar it's simpler than the Spanish one and the words are shorter, you could put tons of in game content and potential actions and effects; that's why The Hobbit shines. Altough further Spanish games were much better, such as Aventura Espacial.
Pulling up games from decades ago instead of the last few years isn't a good benchmark either especially considering the technical limitations that existed at that time.
I'm the last person to propose more LLM usage, but there is a reason DnD has exploded in popularity in recent years despite fancier games and graphics existing, and it's not because people find text/story telling restrictive on an immersion or technical level. If a Zork was released today with a hypothetical adaptive parser with world coherent output (big ifs) I think it'd be a huge hit personally. Though to be clear, I'm not saying someone could build it on an LLM.
As long as people still enjoy books I believe they will still want to interact with it if possible.
That's just their nature: they are very inexpensive to make. The original question was whether people find them fun and engaging. Clearly they did in the past. Though nowadays their standards have risen a lot. Even graphical adventure games (like Monkey Island) have long fallen out of favor due to a lack of action elements.
