Hehe, the first screenshot shall be planet Earth. Yes the good old terra.
Second is coalition planet Murmansk, a planet which fills 1/8 of a 200 x 200 system.
Me personally think a cityscape would be to much. Just a simple industrial mining surface, like Pitsburgh.
A fully developed and settled planet would cause the effect of high ship traffic. So it would be much harder to keep the system and the planet as a secret. An invitation to BHG, bretonian and liberty forces to say hello.
