What is SCI?
SCI, which Sierra referred to as both the “SCript Interpreter” and the “Sierra Creative Interpreter”, is a p-machine style virtual machine for executing platform- independant, object-oriented code. SCI was designed for 16 bit little endian computers, although there were later attempts to create 32 bit versions, LSCI, and SCI32. SCI was exclusively used by Sierra On-Line, Inc., to run its computer game series, with titles like Leisure Suit Larry 2-7, Space Quest 3-6, King’s Quest 4-6, Quest for Glory 1-4, and several others.
