Adventure Game Interpreter (AGI)

The Adventure Game Interpreter (AGI) is a software system developed by Sierra On-Line in the late 1980s to create and run point-and-click adventure games. It provides a framework for designing interactive stories, managing graphics, text, and user input seamlessly. Essentially, AGI acts as a virtual engine that interprets game scripts and assets, allowing developers to craft complex puzzles, dialogues, and environments without building a game engine from scratch. Its modular design enabled the widespread popularity of classic adventure games like King's Quest and Quest for Glory.
