Yeah - it's funny that my local leisure centre has more parking spaces than some of these intergalactic trading hubs.
I just think that high population systems should feel 'busier' somehow. I mean - shouldn't there be a line of interplanetary shuttles between Earth and Mars for a start?
Reminds me of a planet near Fular back in Beta. It was massive with four Coriolis stations and 5 or 6 outposts, and a population in billions, they neither imported stuff, nor did they export stuff, they had 10 ships available in shipyard though....
Guess they just wanted to be left alone.
They have probably inbred themselves into amoebas by now......
