I really like Starlight Emperium. It's fresh, somewhat catchy, and immediately piques my curiosity.
The reason I dislike Empires in Exile is that it reminds me too much of the title of a generic RTS or TBS game made in the early 90s such as "Dune Wars", "Cosmic Conquest", "Age of Empires" etc.
I think you'd have more success appealing to a modern audience.
