This is a brainchild of mine and has a devoted site: ImpScript.

ImpScript is a simple scripting language for creating classic text adventure games – the kind of thing that first appeared around the time computers like the ZX Spectrum and Commodore 64 started to enter homes.

I have developed a custom editor to create the games, and the scripting language is the fruit of my previous work on chatbots and things like AIML and various natural language projects.
