1	According to Website/TheOtherWiki, a general ArtificialIntelligence (AI) is an engineered system that perceives its environment and takes actions that maximize its odds of successfully achieving certain goals. While this definition is applicable to some game-playing [=AIs=], such as the TabletopGame/{{chess}}-playing [[https://en.wikipedia.org/wiki/Deep_Blue_(chess_computer) Deep Blue]] and TabletopGame/{{go}}-playing [[https://en.wikipedia.org/wiki/AlphaGo AlphaGo]], "artificial intelligence" in MediaNotes/VideoGameDesign instead usually refers to all sub-systems that govern the behaviors of [[NonPlayerCharacter non-player characters]] and enemies. Whereas general AI is viewed as an end in itself by the academia, video game AI is just another [[Administrivia/TropesAreTools design tool]] for game developers to craft gameplay experiences for the players, and a "mere" ''[[FeigningIntelligence illusion of intelligence]]'' is, in most cases, more beneficial to their WillingSuspensionOfDisbelief than actual [[PerfectPlayAI optimal decision-making]].
