I like how everyone plays the same story but has extremely different ideas as to what is going on with the main character(your character).
The person over me plays his sith like, and i am venturing out on a guess here, dark-sided killingmachine. While for example, i play my Sith Warrior as a ruthless, but more lightsided roamer, she doesn't give a crap about political power or any of that scheming nonsense! Heck she doesn't even mind being Darth Chubbyface's errand boy, it got her a ship and when he finally becomes to annoying to put up with, she'll just do a Malgus and roam around, conquering planets and chilling out.
My personal wish though is that in the inevitable expansion pack, we get to hang out with Malgus as our new BFF
