ScummVM, short for Script Creation Utility for Maniac Mansion Virtual Machine, is an open-source software project that serves as a way for nostalgic gamers and retro enthusiasts alike to enjoy some older classic games. Originally developed to run classic LucasArts adventure games that utilized the SCUMM scripting language, ScummVM has since evolved into a versatile piece of software supporting a wide range of point-and-click adventure games from various developers.
