Manhunter 2: San Francisco - PC Games
A sequel to Manhunter: New York, it was released in 1989 and was the last official Sierra game to be released using the dated AGI engine.
AGI (Adventure Game Interpreter) was the development scripting tool used by Sierra Online to create their early adventure games, from 1984 to 1989.
The first King's Quest game originally used a language named Game Assembly Language, or *.gal, by its designer, Arthur Abraham, but when he left, Sierra was unable to complete the game. Since King's Quest was intended to showcase the technology of the IBM PCjr, IBM "donated" its product, AGI, to Sierra to allow development of King's Quest to continue.
When it debuted in the mid-1980s, AGI was innovative and made impressive use of the technology available at the time. Later versions were adapted to use 16-color EGA graphics.
Used in the early classics of Sierra's Adventure games, their first scripting tool was limited to 160x200 resolution, 16-color EGA graphics, no mouse support, and no sound card support.
When rival LucasArts' SCUMM engine was putting the AGI engine to shame in the late 80s, Sierra developed and released the SCI (Sierra Creative Interpreter) scripting language to push games into the next era of computing.
