The Graphic Adventure Creator

The Graphic Adventure Creator, better known as GAC, is a game creation system published to numerous platforms that enables users to develop text-based adventure games with integrated graphics. It includes a demonstration game titled "King's Ransom," which showcases the capabilities of the software and is short but otherwise fine adventure on its own right.

Users interact with the software through a menu-driven interface, allowing them to define game elements such as rooms, objects, and characters. The system supports full-sentence command parsing and includes a built-in graphics editor for creating visual elements to accompany the text. Additionally, it features text compression to optimize memory usage.
