AGI (Adventure Game Interpreter) is a classic game creation system renowned for its ease of use and flexibility, particularly for developing graphical adventure games. Originally released in the late 1980s, AGI empowered a generation of developers to create intricate worlds and compelling narratives without extensive programming knowledge. Its scripting language allowed for the definition of rooms, characters, objects, and complex interactions, making it a foundational tool for many beloved early adventure titles. AGI remains a nostalgic and accessible platform for retro game development.
