High Quality Content by WIKIPEDIA articles! Dunnet is a text adventure written by Ron Schnell in 1983. The game enjoys certain popularity because since 1992 it is part of the default packages in many of the Emacs versions. The word Dunnet is derived from the first three letters of dungeon and the last three letters of Arpanet. It was first written in Maclisp for the DECSYSTEM-20, then later re-written in Emacs Lisp so as to be more portable.
