The interplay between directional limitations for ship maneuvering, shield protection, and weapons fire makes for a practically infinite number of tactical permutations from which the ship captains can decide. Each maneuvers to present his strongest shields to his most dangerous adversaries, while at the same time seeking to generate firing opportunities for his most powerful armaments against his most vulnerable or threatening opponents. When more advanced decision options are added to the basic game system (for example, mid-turn speed changes and reserve battery power for "trick" moves such as "anchoring" an enemy by tractor beam) the gaming situation can become very intricate. Environmental factors like asteroid fields, planetary atmospheres, and minefields further diversify the gaming possibilities. Finally, multi-starship scenarios (and also those involving starbases, battle stations, or civilian convoys) can complexify the gaming experience to suit the tastes of the most sophisticated wargamer.
