The object of the game is to occupy ten planets (you start with five) via combat, negotiation, or shenanigans. Each player drafts two unique powers, each of which breaks the rules somehow. Just for instance, in the last game I played, one player had the power "you start with ten planets, but your planets are only worth half." Eventually I won by causing this player to swap places, but not powers, with me. Some such BS happens every single game, and never the same way twice.
