Game artificial intelligence refers to techniques used in computer and video games to produce the illusion of intelligence in the behavior of non-player characters (NPCs). The techniques used typically draw upon existing methods from the field of artificial intelligence (AI). However, the term game AI is often used to refer to a broad set of algorithms that also include techniques from control theory, robotics, computer graphics and computer science in general.
Since game AI is centered on appearance of intelligence and good gameplay, its approach is very different from that of traditional AI; workarounds and cheats are acceptable and, in many cases, the computer abilities must be toned down to give human players a sense of fairness. This, for example, is true in first-person shooter games, where NPCs' otherwise perfect aiming would be beyond human skill.

Famous quotes containing the words game, artificial and/or intelligence:
“Neighboring farmers and visitors at White Sulphur drove out occasionally to watch ‘those funny Scotchmen’ with amused superiority; when one member imported clubs from Scotland, they were held for three weeks by customs officials who could not believe that any game could be played with ‘such elongated blackjacks or implements of murder.’”

“Nothing strengthens the judgment and quickens the conscience like individual responsibility. Nothing adds such dignity to character as the recognition of one’s self-sovereignty; the right to an equal place, everywhere conceded—a place earned by personal merit, not an artificial attainment by inheritance, wealth, family and position.”
—Elizabeth Cady Stanton (1815–1902)
“A German immersed in any civilization different from his own loses a weight equivalent in volume to the amount of intelligence he displaces.”
