About
SCI, which Sierra referred to as both the "SCript Interpreter" and the "Sierra's 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 4-7, Quest for Glory 1-4, and several others.
The SCI engine in ScummVM is based on the code of the FreeSCI project, used with permission.
History
SCI was initially created in 1988 by Jeff Stephenson to replace AGI. The first game using it was King's Quest IV at the same year of its creation, which was simultaniously released with an AGI edition for lower-end machines.
