a computer strategy game set in outer space. there is a grid of tiles some of which have stars with inhabitable and improvable planets.
Galactic Civilizations bears some similarity to the expand, explore, and conquer gameplay of the Civilization series.
one difference is that combat is not specific to a generic set of predetermined units. rather each player creates their own spaceships with three types of attack and three types of defense. the downside of this approach is that it forces a player to continually create new spaceships to engage in new space battles.
unlike most strategy games which are deadly serious in tone, this game has the aliens make humorous attempts to bully or suck up to their rival (the player).
