idea-

what about retreat from a battle? jump to hyperspace? and one of the enemy ships or your own can carry a "Gravity Wall" (a tech that can be researched, and then the Gravity Wall projector module will be installed on one of your ships) that blocks the enemy ships or you own from jumping?

and when a ship is destroyed, what about escape pods? the crew must survive! the escape pods will be lunched to one of your remaining ships (an option that will only be available when the "rescue" ship will be a large + hull) then the surviving ship will jump to hyper space or be destroy...

the escape pods will be destructible, means the enemy fighters will be able to intercept them.

and when you win a battle and the enemy didn't jump to hyperspace, (because he is stupid or because he can't) you could take the "crew" on the escape pods to your ship and make negotiations with the enemy race if they want them back. you can trade them for your own crew or money, or to kill em!

and if your ship is Large + hull and the enemy ship is Large - hull, you can aboard them! and take their ship! then repair it and make it your own! (only if you win the battle)

my idea...
