Your comment is relevant. Your character, whatever the session in which you play, will not have a unique personality. As in real life, people have multiple personalities. At work they are serious people in the evening, they are exotic while partying, one day they are friendly, the next day unpleasant. One day they are explorer to pick up mushrooms. The next day they are trader to sell their mushrooms, and if they not have of mushrooms, they steal mushrooms, at another person. Personally, I would not be shocked if in the game, I met a commander with multiple personality, who one day said "hello" and the next day asked my cargo. ----But it is nevertheless a little incoherent relative to the history of each session, and overall history. So the ideal would be indeed a unique name of Commander, per session.
