Video Games Encyclopedia

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 to hundreds rather than hundreds of thousands.
