Ouch
You're a heck of a lot farther along than I am. I started out in the bottom corner of the map with a black hole sector above me and only one worm hole out of my system. I expanded into four other systems and met three races including the Xiati. I have partnerships with two races so they are showing me their designs/maps. The Xiati have dreadnoughts and I have battle cruisers. Needless to say, I started building mine layers in the hopes of preventing the Xiati from finding me. It is good to know that mines work.
