You are a flagship commander of one of the great galactic superpowers, navigating the fringe of the known galaxy in an effort to claim and colonize the many bountiful star systems in the region. Expansion can be achieved through rapid peaceful occupation, but you must also use the military resources at your disposal to seize enemy outposts and to protect your own. Although this is new territory for you and your competitors, a variety of alien species are native to the newly-charted sectors... earning their loyalty will go a long way towards deciding who will be the master of the Galaxy's Edge!

Your overall objective in the game is to score the most points at the game's end. Points are mainly earned for building colonies in the many star systems of varying value. Bonus points can be won by earning the loyalty of various alien species while satisfying their specific requirements.

Throughout the game you will need to support your colonization efforts with military strategy, which in turn will allow you to conquer valuable opposing colonies and thus score more points. Obtaining—and keeping—alien loyalties will be an important factor in determining a winner, and the diverse Event cards can be used to further your goals in a number of ways.
