I Don't really understand the logic behind maps
I guess one map could be an entire solar system, with all it's planets, and stations orbiting them
And to travel between systems you use FTLengines, wich are not accurate enough for interplanetary transport
At least it's how I imagine it, it would justify ships cruising with thrusters from one station to another, instead of instantly FTL Jumping toward it's destination
One other suggestion, the place where ships are able to safely exit FTL cruise (where they spawn in the map) could be Beacons Stations, and the faction able to control it (theorically) control the system
Hope It helps, and that I am not too late
