I enjoy text-based adventure games. Even though I loved Myst, Riven, The Space Bar, Zork Nemesis, and others, there's something (perhaps nostalgic) about the natural-language-like interface of a text adventure that keeps me coming back. In the early '90s I wrote an adventure creation language, Archetype, and some games you can play in it.
I own a Macintosh Performa, running MacOS 7.6. Part of
what I like about AppleScript is the degree to which its syntax
resembles an adventure game! Apple has created a language
that resembles a natural language to perhaps the greatest degree
possible. Here's a collection of fairly useful AppleScripts
that I use on my own machine.
