SCUMM

Script Creation Utility for Maniac Mansion (SCUMM) is a scripting language developed at LucasArts (known at the time as Lucasfilm Games) to ease development of the graphical adventure game Maniac Mansion.

It falls somewhere between a game engine and a programming language, allowing designers to create locations, items and dialogue sequences without writing code in the language in which the game source code ends up. This also allowed the game's script and data files to be re-used across various platforms. SCUMM is also a host for embedded game engines such as iMUSE (standing for Interactive MUsic Streaming Engine), INSANE (standing for INteractive Streaming ANimation Engine), CYST (in-game animation engine), FLEM (places and names object inside a room), and MMUCUS. SCUMM has been released on the following platforms: 3DO, Amiga, Apple II, Atari ST, CDTV, Commodore 64, Fujitsu Towns & Marty, Apple Macintosh, Nintendo Entertainment System, DOS, Microsoft Windows, Sega Mega-CD and TurboGrafx-16/PC Engine.
