A graphic adventure game is a form of adventure game. They are distinct from text adventures. Whereas a player must actively observe using commands such as "look" in a text-based adventure, graphic adventures revolutionized gameplay by making use of natural human perception. Eventually, the text parser interface associated with older adventure games was phased out in favor of a point-and-click interface, i.e., a game where the player interacts with the game environment and objects using an on-screen cursor. In many of these games, the mouse pointer is context sensitive in that it applies different actions to different objects.
