SCUMM stands for Script Creation Utility for Maniac Mansion. It is a game engine developed by Lucasfilm Games in the late 1980s, primarily used for creating graphic adventure games. The engine allows developers to script game events and interactions, making it easier to design complex narratives and puzzles. The first game to utilize SCUMM was Maniac Mansion, released in 1987. This engine became the foundation for many popular titles, including The Secret of Monkey Island and Day of the Tentacle. Its point-and-click interface revolutionized adventure gaming, allowing players to interact with the game world intuitively.
