BTW. What have the leader personality traits for an effect? Is there a limit of how many i can give to a leader and why should i use a negative trait?
They are for story writing purposes only, I belive. As Steves said in the above post, he created Aurora primarily to help in writing, so adding some personality traits makes a lot of sense, even if it doesn´t directely influence the game (of course, you can use those traits in-game too, if you roleplay your game. For example, a risk-taker admiral will probably order his fleet to boldly attack, were a cautious admiral will hold back much more).
Edit: Ok, I give up
