Might or might not be associated with Turn Based Strategy and Role-playing games.
In a classical turn-based system, only one character may act at a time; all other characters remain still, with a few exceptions that may involve the use of special abilities. The order in which the characters act is usually dependent on their attributes, such as speed or agility. This system rewards strategic planning more than quickness. It also points to the fact that realism in games is a means to the end of immersion in the game world, not an end in itself. A turn-based system makes it possible, for example, to run within range of an opponent and kill him before he gets a chance to act, or duck out from behind hard cover, fire, and retreat back without an opponent being able to fire, which are of course both impossibilities.
