I've finished setting up the defenses of my colonies. They have 24 Rockets, 12 L. Lasers, 6 H. Lasers, 6 Ion Cannons, and 3 Gauss Cannons each. While that can be broken, I've also moved everything that was on them to my homeplanet. All thats left on each are 5 S. Cargoes and a Recycler to ship what they produce to my home planet and pick up resources that get shot up in their orbit. I'll ship the necessary resources to them when I want to upgrade something.
Right now I'm setting up my tech so I can produce Battleships. Once that is done I'll create my real colonies, worlds far away that can support themselves and become major powers where they are located.
