reserved for certain computer strategy games, to distinguish them from real-time computer strategy games. A player of a turn-based game is allowed a period of analysis before committing to a game action. Examples of this genre are the Civilization, Heroes of Might and Magic, Making History, Advance Wars and Master of Orion. TBS games come in two flavors, differentiated by whether players make their plays simultaneously or take turns. The former types of games are called simultaneously executed TBS games, with Diplomacy a notable example. The latter games fall into the player-alternated TBS games category, and are subsequently subdivided into (a) ranked, (b) round-robin start, and (c) random, the difference being the order under which players take their turns. With (a), ranked, the players take their turns in the same order every time. With (b), the first player is selected according to a round-robin policy. With (c), random, the first player is, of course, randomly selected. Almost all non-computer strategy games are turn-based; however, the personal computer game market trend has lately inclined more towards real-time games. Some recent games feature a mix of both real-time and turn-based elements thrown together. Turn-based tactics (TBT) Turn-based tactics (TBT), or tactical turn-based (TTB), is a genre of strategy video games that through stop-action simulates the considerations and circumstances of operational warfare and military tactics in generally small-scale confrontations as opposed to more strategic considerations of turn-based strategy (TBS) games. Turn-based tactical gameplay is characterized by the expectation of players to complete their tasks using only the combat forces provided to them, and usually by the provision of a realistic (or at least believable) representation of military tactics and operations. Examples of this genre include the Wars and X-COM series, as well as tactical role-playing games such as the Jagged Alliance (series), Fire Emblem series and Final Fantasy Tactics. Wargames Wargames are a subgenre of strategy video games that emphasize strategic or tactical warfare on a map, as well as historical (or near-historical) accuracy. The primary gameplay mode in a wargame is usually tactical: fighting battles. Wargames sometimes have a strategic mode where players may plan their battle or choose an area to conquer, but players typically spend much less time in this mode and more time actually fighting. Because it is difficult to provide an intelligent way to delegate tasks to a subordinate, war games typically keep the number of units down
