Some games, such as strategy games like "Civilization III" or role-playing video games such as "", use AI heavily, while others, such as puzzle games, use it sparingly or not at all. Many game developers have created entire languages that can be used to program their own AI for games via scripts. These languages are typically less technical than the language used to implement the game, and will often be used by the game or level designers to implement the world of the game. Many studios also make their games' scripting available to players, and it is often used extensively by third party mod developers.
