Game Engine: Adventure Game Interpreter (AGI)
Group DescriptionThe Adventure Game Interpreter (AGI) engine was first introduced by Sierra for its early avatar-moving adventure games, pioneered by King's Quest (1984), wherein the engine was briefly referred to as the GAL (Game Assembly Language).
The game engine was designed by Arthur Abraham as a replacement for their text-adventure-with-pictures ADL engine used in their High Res Adventure games, and was initially meant for the IBM PCjr (and, happily, Tandy clones) but was subsequently ported to other platforms. Manhunter 2: San Francisco (1989) was the last commercial game published by Sierra using the AGI engine as the engine could no longer compete with other adventure game engines at that time, and was replaced by the Sierra's Creative Interpreter (SCI) engine. The AGI engine however, continues to be used to create unofficial (shareware/freeware) AGI games by nostalgic individual programmers and companies.
Not to be confused with the Game Engine: Adventure Game Studio (AGS) game group.
