But realism is very important, especially in games like this. After all, if every faction had ISD's, Mon Cal Cruisers and if Luke was a 10ft giant with lightsabres for arms, it wouldn't be a good Star Wars game now would it?
As I pointed out with the Axis & Allies example, you don't have to give evry side the same sort of unit in order for the game to be balanced. I personally would rather see the Consortium have cheaper, smaller ships rather than an ISD killer.
Perhaps rather than having a battleship, the Consortium could have had a 'ramship' that is unarmed and small, but flies straight into an enemy battleship, damaging it.
