I was thinking about ideas like... make some sort of basic motivating way to start the game...
Like a very straight forward thing.
Like you are a new recruit in the navy or something and this is what you will be supermotivated to role play while you get to know the game, and once you got to know it you'll see a new possibility to slip into some other faction, which is also very motivating to play.
I guess the first obvious faction would be Order, the second nomads, or navy, or others.
But there would have to be very specific learning on how to role play these factions correctly, kinda like you learn how to play a game in single palyer campains.
With every mission you learn more about the game.
Kinda like the starcraftt campains... you learn more about the game in every step you take. You start with humans, then zerg, then protos. Same could maybe be done for the basic freelancer factions, which are suposed to be the most numerous
