Solo Playthrough - Imperials - Mint Imperium

About Mint Imperium, from BoardGameGeek:

In Mint Imperium, you control the vast Imperial navy or the ragtag group of Rebel forces. You will command your leaders and your starships as you subjugate or rally planets to your cause. Each side has a different win condition so you will need to adjust your strategy depending on which faction you play. As the Imperials, you will have a large amount of units and a star fortress that can obliterate planets. You must find and destroy the hidden rebel base to win. As the Rebels, you have a smaller amount of units, but they can be formidable in combat. Employ hit-and-run tactics and disrupt the Imperial agression. You win if you can survive long enough and inspire the galaxy though decisive victories. -description from the publisher
