I will admit I really don't want to go NR however if no one else does it I might have to.
I'd consider doing Mon Calamari if neither of you two really want to and we end up needing it, though a Sithish guy/Prob Knights Ren precursor-type who has some very limited distant contact with an inferred Snoke/i.e.Plagueis damnit! is my first choice. Basically my entire character purpose in this case is to disrupt the delicate peace the Galactic Concordance brought between NR and IR elements by sowing chaos.
*eyeballs the signatory* COUGHTRAITORCOUGH ahem. scuse please.
I think the game will flourish best if we get at least 2 players for each primary loyalty, allowing distinction then between elements such as First Order, Imperial Remnants, The True Empire, New Republic, Resistance etc. A player could even fall away I suppose and take a story path leading to more ambiguity, or possibly even go entirely as an Independent world/Legend to begin with..
