Pax Galaxia starts out as intergalactic sumo wrestling. No, it isn't two prodigious BEMs (Bug-Eyed Monsters) trying to shove each other out of a gravity well. As the admiral in charge of a space fleet based in a given star system, you order your ships to hit certain force points in the galaxy and, ideally, drive your enemies progressively away from your end of the galaxy. In the tradition of other so-called real-time strategy (RTS) games, your opponents (artificial or human) are making the same kinds of moves at the same time. If you pay attention to your defensive lines, you can quickly push the enemy back and extend your "beneficent" influence across the simulated galaxy. If you aren't careful, your fleets and empire can quickly shrink to nothing.
