The Capital ships are the heroes of the game, you remember battles by the actions of your Capital ships and their brave crews.
Example: My Current Beta 2 Game - 45 Minutes In
I had just achieved another great victory for the Traders Union (Name of my Empire), we had colonized the Ice World of Makhaon. My Flagship the Kol class Battleship Korsev was on station to defend against possible encroaching enemy forces. My main fleet was recalled to the homeworld for defense against pirate raiders popping up in the region. A few standard hours later (3 Minutes) my first Crystal Mine was complete, and the motions that would cause many to weep had begun.
It started with just a small pirate force entering the gravity well of Makhaon, I sent the Korsev to intercept and destroy the dastardly vile forces. She was up against 5 Corsair pirate vessels, but through excellent leadership and the hard work of a brave crew she overcame odds and destroyed the pirate raiders. But fate was against us that day...
I ordered the main fleet to come about and charge for our new frontier world of Makhaon . Comprised of Cobalt Frigates, LRM Frigates, and a prototype Carrier Cruiser they charged ahead towards the defense for our new world. But like many times before fate had a different path.
Unknown to our intelligence network the Trade Coalition had chosen Makhaon as well for their first frontier world. The Korsev recently gaining a level in experience (Level 4) from the previous conflict rushed forward valiantly to meet this new threat head on. The Commander and Crew of the Korsev fought and gave their lives so reinforcements could arive and save the colonists of Makhaon. Their sacrifice will be remembered and their crew never forgot.
That is why your capital ships are your heroes.
