Build a trade empire across the galaxy and stop your rivals from doing the same. There’s a whole galaxy to explore - and it fits in a mint tin. You are an interplanetary trader, building your empire from the galaxy's many and varied Worlds. Every turn you will use two actions to build rows of matching resources by playing new World cards or upgrading your Worlds. Will you expand with more Worlds, or stack as much as you can on your existing Worlds before your foes hit you with a downgrade? —description from the designer
