I'll grant it isn't completely unworkable but still the drive charge times and ranges make Fleet in Being a little more difficult to pull off.
Use one of the many 'hidden systems' which aren't on the map. There are lots of star systems that don't have garden worlds in them between the nice white dots on the space map.
As for space battles, the same can be said if you put two blank ground maps on the table and deployed ground forces. And, there are plenty of places on a planet that will fit that for a potential firefight engagement. Drop port, anyone? Kilometers of concrete. So, wrinkle - the entire map is pavement. Skidding rules are in effect!
One of the reasons Star Trek and other very fast Sci-Fi naval combat could be so dynamic is because you could flee to built up terrain like a nebula or asteroid belt in short order.
BT Naval combat has only two points of interest: the launching point, and the destination. IE- Jump Points and the planet-in-question. Unless the planet has rings, then yeah, things are out in the open.
Honestly, where ECM complicates ground games, some form of using ECM as deployable terrain might help the space game. I kinda recall it being something in Jovian Chronicles, which is about space Mech combat, with warships.
