DunnetPredecessor

Every copy of GNU Emacs comes bundled with the text adventure Dunnet [0]. Dunnet was originally written by Ron Schnell in 1982, as a Maclisp program running under TOPS-20. [1] In 1992, he ported it to Emacs Lisp; however, the Emacs Lisp version is more than just a simple port of the original, it extends the game with new rooms/items/puzzles, but also removes MIT-centric content–e.g. the "endgame" computer at the end of the game was originally named MIT-SALLY, was located at MIT, and was accessed via Chaosnet–the GNU Emacs version removes all those (dated) MIT references–although the GNU Emacs version contains (obviously intentionally) equally dated (albeit more widely recognisable) content such as a VAX 11/780 [0] https://en.wikipedia.org/wiki/Dunnet_(video_game) [1] Original is here: https://github.com/Quogic/DunnetPredecessor/blob/maste

I always found the parallel-arrays (or rather parallel-lists) structure of Dunnet aggravating. Isn't there a better textual representation for an adventure game map than this?
