That’s when you may be able to form or become part of a galactic federation. You’ll also be dealing with trade, alliances, federations and border control, but federations offer grander possibilities. They are led by a president, elected from the member civilisations at regular intervals, and that player (or AI) has control of all foreign policy and of the federation fleet. When you design the ships for that fleet you have access to all the modules from every race in the federation, allowing for combinations unavailable elsewhere. Whether you choose to build a peacekeeping force, an ambassadorial outreach program or a terrifying overpowered fleet of battleships is entirely your choice, but it’s wise to keep in mind that you may lose the next election and cede control of your creations to another leader.
