Hey! I hope a little self promo here is alright! The game I’ve been working on is inspired by these older text based adventure games, and its a bit of a homage to that style. I’ve been building my own text parser for it. Its been a hobby project of mine for the last couple of years and is nearing completion.
It might not fit the bill completely in that it doesn’t really require natural language, but maybe it’ll help scratch the itch a little? There is a demo up on Steam ( store.steampowered.com/app/3919240/Soulfused/ ) and Itch ( confoxing.itch.io/soulfused ) If you do give it a try I would love to hear your thoughts!
Soulfused is a modern take on the classic text adventures from the early days of computer gaming. Dive into a dystopian future ruled by an empire focused on conquest and control. Take on the role of a newly converted Soulfused; a part human/part robot soldier in service to the Empire.
