How about playing the faction game?
Choose a system you like, has a couple of good trading routes etc. Pick a minor faction to work for and only do their missions and only trade to a station they own.
Become friendly then allied and either
1) If they are the owning faction of the system, see if you can get them to expand into nearby systems.
2) If they dont currently own the system, build them up to a point of civil war, once they own the system go to point 1.
Hopefully later this will also expand out into new systems ferrying goods to build new stations.
I dont care for the credits/ship grind, it is something that happens while i am doing something else. Friends and I are currently trying the above within a little 50ly bubble we have currently come to call home

. I understand there maybe other players working the area that are detrimental to our efforts but im having fun, missions offered are becoming better paid, a nearby system that is one of my main trade routes has gone into civil war so i am also fighting on their behalf.
I do hope this is something FD add a little more depth to. Even though i am having fun doing the above it would be nice to know what my choices are e.g I have chosen to work for a cooperate group but what difference would it of made if i choose the democratic/political faction if any?. How do i know if my chosen faction are currently winning the civil war? Some kind of local entry in galnet would be nice to let you know what is actually happening locally or some kind of info in the factions tab other than just a Civil War Pending label or something visual like conflict zones ebbing and waning depending on the state of. Some of this may already be happening and im just not noticing, I have noticed a change in number and position of conflict zones but i am just not seeing the connection at the moment.
Never the less this is what i am currently doing, means i am doing a little of everything trading, missions, bounty hunting, conflicts etc all with the intent of expanding my currently chosen home system and its controlling faction.
