The AGI (Adventure Game Interpreter) engine was used by Sierra in their early adventure games.
It was also used in a digital "christmas card" given by Sierra to computer stores in 1986 to demonstrate the capabilities of the computers at the time, as well as the capabilities of the AGI engine. The program was designed to be started in the morning and run throughout the entire Christmas day.
The AGI engine in ScummVM is based on the code of the Sarien project, used with permission.
