There have been many good adventure game creators on the Atari ST such as Stac. In the public domain one that stands out from the rest is the STOS Adventure Creator which allows you to create text based adventure games using the STOS Basic programming language. This was followed up by the STOS Graphic Adventure Creator which, as the name suggests, allows you to create graphic adventure games using the point and click interface.
STOS ADVENTURE CREATOR
The STOS Adventure Creator was my very first ST program and one of the most popular. It is a complete system for producing text-based adventure games with STOS Basic.
STOS GRAPHIC ADVENTURE CREATOR
The STOS Graphic Adventure Creator allows users to create mouse driven “point and click” graphic adventure games using STOS Basic.
