Hi - playing my second real game on 7/7, enjoying it lots and sort of getting the hang of it.
I have a couple of systems which have nothing of value in them, but lie between important planets owned by me, so I want them to be quick and safe to move through. I have cleared everything except the AI's command ship, then placed an outpost with a Zenith Time-Space Manipulator inside a weak forcefield, plus a mixture of Spider-V and Missile turrets.
This seems to keep them clear of AI nuisance, but Marauders seem to trash this regularly (I have them on 4). Why do my turrets not seem to target the Marauder ships (I looked, one seems to have normal "Polycrystal" hull type)? Is there any static defence that is a useful counter against them?
