Fourth, it differs from many wargames in that each unit is not simply a set of offensive and defensive numerical ratings; rather, each ship has a variety of individual weapons and resources, each employing their own tactics and counter-tactics. Thus players are able to utilize, e.g., boarding parties, shuttles, tractor beams, electronic countermeasures, etc., permitting many more tactics than in the average wargame, requiring much more documentation. It is this which allows the game to become a science-fiction experience, and puts it in concert with many literary elements of "Star Trek".
