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.
