LLMs have an obvious application of removing the command limitations. https://github.com/UlfarErl/lampgpt

"FYI, it is now possible to play all of the Infocom games with a phenomenal parser using LampGPT, with just ./lampgpt.py -O gamename."

Ugh, I'm so glad this exists; I tried some text adventures a few years ago and struggled to get into them due in part to having to cooperate with a rather baroque user interface.

I feel like this could really open them up to a new generation.

I do see a lot of potential application for LLMs around having a natural dialogue with an NPC in future games. Also LLMs to well-defined structured parser instructions might finally enable Strongbad to "get ye flask".
