I am also interested. I've been curious what strategic elements a real space combat situation (on the scale of a solar system) demands, and if an interesting game can be made out of it.
I'm using real engines and fuel consumption (draco thrusters from Space-X) and somewhat realistic ship mass (3t) and I can tell you space combat is virtually impossible. Especialy "space pirates" kind of fight where they wait in ambush mid way. I fly mostly around jupiter and "eyeballing it" from one moon to another is impossible. You can fly reasonably easy within few km from space station but that's it. For everything else expect delta V more than km/s. Guided missiles would imho be impossible with FPS realistically achievable in game. Dunno about lasers, i'm trying to keep it real.
