SCUMM, meaning Script Creation Utility for Maniac Mansion, was developed by Ron Gilbert in 1987 for the LucasArts, then Lucasfilm Games, adventure game Maniac Mansion. Since then SCUMM has been used for numerous adventure games aimed at a variety of different audiences.
In most SCUMM games the player controls an inventory that can be filled with various objects found throughout the game. Using a variety of verbs, that usually include and stem out from talk, pick up, open, and look, the player can interact with the ingame world. Eventually in games like The Curse of Monkey Island these actions had been whittled down to various icons such as eye, hand, and mouth. In most games in order to solve puzzles the player must use certain inventory items with other ingame objects.
