I love the rock paper scissors system of GCII
Beam weapons+defenses
Projectile weapons+defenses
Missile weapons+defenses
It is like the opposite of the rock paper scissors formula, it is a great unique system
What's that? they said every piece has a function? Well does that sound fun if the ship can take casualties in battle by losing important pieces of the puzzle?
Ex. Lets say there was this colossal ship with weapons so powerful that it can obliterate anything in its path, right?
Scientist slave: "sir, by my calculations we can fit so much firepower on this ship we can say screw defenses"
Drengin: excellent, load that ship up with our finest black hole guns!
50 weeks later
Drengin leader: Captain, we have so many weapons, we can render earths forces defenseless, lets have a transport follow us.
Captain: They shall pay for resisting the mighty Drengin.
>> small ship with a laser mark I on it arrives from hyperspace
Captain: rip that thing to shreds
>>laser strikes the only hyper drive engine and blows up from all the firepower
Captain: aha, those scum think such a weak ship can stop me?
>>slave enters the room
slave: Captain, it seems we cannot move, apparently our hyper drive is down
Captain: WHAT?
>> Brutally murders the slave
Captain: get a constructor out, asap, I want the hyper drive fixed.
END TRANSMISSION:
Basically it would be so funny if you could your ship randomly knocked out parts of another ship and they get weaker and weaker if your ships defenses not adequate. It could be a random lucky day where you ship knocks out the only hyper drive the ship has, and requires assistance from a constructor/repair vessel to move again. This feature could be very entertaining and combined the the hp system it would blow up if the ship have no parts left and/or if the ship runs out of hp points.
It adds a whole new level of strategy even if it is random, since you obviously have no control on how good that ship captain and its crew.
