AGI was the in-house, parser-based EGA game engine that Sierra used for its adventure games in mid-80s (e.g. Police Quest 1, King’s Quest 3, Leisure Suit Larry 1). King’s Quest 4 was finished with AGI, but then Sierra decided to upgrade the game to the newer SCI engine which allowed for better graphics (SCI engine was later used for Police Quest 2, Colonel’s Bequest, and Hero’s Quest 1, to name a few). This AGI version was actually released, but was pulled from the shelves and replace with SCI version very quickly.
