This is the view of the galaxies near your galaxy. To see this view, requires a whole lot of research and very advanced space travel technologies. Very advanced Faster-Than-Light technologies allows you to travel thousands of times faster than light and discover the deep cosmos, and bring your influence and products to The Universe.
Your galaxy may hold thousands of civilizations you already know everything about.
Now you have the opportunity to discover civilizations in new galaxies!
Contact other galactic empires and establish intergalactic trade, or drag a wave of blood through the stars. But wars are expensive, and galactic wars infinitely more so.
Can you even hold on to the systems you conquer?
