orbiting defensive platforms wouldent work the reason for this is that sapce is 3D. You can simply go over the defensis. I propse planet stationed defensis like missile batteries and fighter hangers that can be built like a planetary improvement and at lev 1 it can have like 2 fighter groupes and it gose up by 2x every upgrade after that. Maby still have orbiting defensive platforms to defend orbating stations and stuf. What do u guys think?
