Strategies

Strategies are obviously part of strategy games. There is some overlap between strategy and tactics.
Strategy, according to the 10th edition of the Concise Oxford Dictionary, is
#"a plan designed to achieve a particular long-term aim."
#"the art of planning and directing military activity in a war or battle. Often contrasted with "tactics"."
Derived meaning is "a plan so devised."
All of the games we cover are considered to be turn-based strategy games. At each turn, you employ tactics, but ideally that is part of a strategy aimed at eventually winning the game. Examples are eliminating all opponents (preferably the strongest or most advanced first) and colonizing Alpha Centauri.
Strategies differ in detail from game to game. We can list and classify them accordingly. Each article about a strategy for a game can be categorized under the specific game or group of games and under a suitable "strategy" category. When we see what articles have been written, we can gradually create categories that fit.
