Yea, Shagohad got the point. It's quite unfortunate that you can't say assign some turrets to some targets, it would allow a navigator to move ship around to avoid fire and align the ship to deal more damage to the enemy while the battleship goes on firing, and with weapon groups you can control energy consumption. Oh well, dreams and dreams...
@Jinx: that reminds me of something, reminds me a lot... oh yes, that's Freespace 2. I was saying about interceptable missiles/torpedoes a while ago. Massive damage, but slow as hell and can be blown by fighters before they hit the target.
