A strategy game or strategic game is a game (e.g. video or board game) in which the players' uncoerced, and often autonomous decision-making skills have a high significance in determining the outcome. Almost all strategy games require internal decision tree style thinking, and typically very high situational awareness.
The term "strategy" comes ultimately from Greek, meaning generalship. It differs from "tactics" in that it refers to the general scheme of things, whereas "tactics" refers to organization and execution.
