SCI
CONCEPT
SCI stands for Sierra's Creative Interpreter and was a tool developed by Sierra On-Line to replace the AGI (Adventure Game Interpreter) engine. Games created with SCI featured more colors (from 16 up to 256) and higher resolutions (from 320x200 up to 640x480), as well as sound card support.


Created by Jeff Stephenson (Person), Sierra's Creative Interpreter was designed as a replacement for Sierra and IBM's older technology, AGI (Adventure Game Interpreter).

SCI was developed from 1988 to 1996 and had five major versions.
