1 - QTads 1.6c QTads is a GUI interpreter for Tads games, running under Unix-based systems (it has been tested in Linux, Mac OS X and FreeBSD, but it should compile and run in many more, like Solaris and Irix). Tads is a programming language for implementing Interactive Fiction (text-adventures). If you ever played an Infocom game like “Zork” or “Trinity”, or the classic game “Adventure” by Crowther and Woods (also known as “ADVENT”; it has also been ported to Tads), then you know what this is about.
