Turn-based tactics

Turn-based tactics (TBT), or tactical turn-based (TTB), is a computer and video game 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.

The gameplay of turn-based tactics game is the stop-action counterpart to that found in the real-time tactics genre, and as such contrasts with other current wargame genre. For instance, in large-scale turn-based strategy games battles are generally abstracted and the gameplay close to that of related board games, and real-time strategy games de-emphasize realism and focus on the collection and conversion of resources into production capacities which manufacture combat units thereafter used in generally highly stylised confrontations. In contrast, turn-based tactics games' military tactical and realistic focus, emphasis on executing intricate and well thought through plans and comparatively short risk/reward cycle usually provide a distinctly more immediate, intense, careful and meticulous experience of battlefield tactics and mêlée than strategy games of other genres.

As suggested by the genre's name, also fundamental to turn-based tactics is turn-based gameplay. The genre has its roots in tactical and miniature wargaming, the recreation of battle scenarios using miniatures or even simple paper chits using relatively intricate rules. Compared to other strategy games, games of the turn-based tactics genre often have distinctly detailed and complex environments due to the tactical implications of elevation, hard cover and line of sight. Further, in most turn-based tactics games a player's force is maintained between battles. This allows units to become more proficient as they gain more battle experience and coupled with the often small and specialised squads used, can even encourage an affinity between the player and his or her troops, breaking down the stereotypical anonymity of the expendable, mass-produced units found in strategic games.
