And milsims like DCS have modelled that for ages, but as far as space games go? It's still a stupid dogfight craze all around and 40km is sadly insanely big. Children of a Dead Earth is such an outlier it's not even funny.
That's the thing I don't get with modern space games, BVR combat doesn't exist. I get Elite went for the whole WW2 era in space combat dynamic, but if Star Citizen wants to do something different why not focus on realistic engagement ranges? You could have pretty bonkers battles at extremely long range as you both maneuver to get closer to each other. Using natural obstacles and current day techniques to defeat missile shots.
I'm flying the F-14 Tomcat in DCS at the moment that uses the Phoenix missile system with ranges up to 100nm (on paper, the actual ranges are more like 30-40nm).
But nope, it's just billion dollar space ships at 400 yards as always.
