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.
