Funny thing is that you would expect costs to go down as the system is developed and established from a gameplay perspective as well as common sense. Sure, the first station costs a lot: There's noone here, you gotta import everything, start from scratch. A bit like starting a real life colony from scratch.
But once you've established a dozen outposts, settlements, installations, etc... you figure it gets easier.to add another one, rather than more expensive. Now you have thousands of people living and working here, producing and manufacturing stuff, making money, etc.
Frontier seems to think otherwise lol. Not just a "nope" but actually the complete opposite. I'm a bit baffled to be honest
