With selling ressources, I get along now. It's just counter intuitive to sell ressources, which I will need later for construction.
How can I get information about the enemy ships like armor, weapons, shield etc. with numbers?
It's impossible to destroy even a single ship of a regular enemy. (Mashine AI and Sectiod are instant suicide anyways. No idea how to salvage menace ships to research their technologies. Perhaps I need 10 fleets.)
Shield strenth, shield recovery, armor and repair rate are too high. Without any detailed info on the enemy ships, I can not figure out, what to research for counter. I am afraid I even need second tier weapons. And better shields/armor too. Perhaps I have no chance either, because at the time I get the technology, the enemy has even better protection and weapons.
