Unrealistic?
No. Eve is scifi, fiction with a jist of reality, as we humans, with the extension of our intellect, understand that reality in space time.
While we might argue that NPC stations need windows, also that space ships need wheels, but in the end, we have to align to how the author(s) wanted us to perceive his world. Did you know that some people like the fact of not being able to see or seen by others from the outside?
But okay, let’s say that CCP does provide you with a window (as citadels have that potential already), still though with stations, not being ships (which has dscanning modules), you won’t get to see the overview window.
Unless perhaps, if CCP adds such module to the station - which if you don’t know yet, will cost some dev / art / recalibration investment and time. And therefore will escalate to requiring an in-game fee for such services. So I’m arbitrating here, but I think a fee of 150,000,000 ISK, per 30 seconds, per player, sounds a decent enough amount for this extra station service. And to be fair to Citadels and other player owned structures (vs NPC stations), the inStation-Overview service will be reduced to 15,000 ISK as a one time fee/day. How does this sound?
