Thank you Simon.

I probably did not make this clear enough. After conquering 10 regions, even if your faction leader does not die, please pass on the game.

Similarly, if your faction leader dies before you conquer 5 territories, by all means keep playing.

Also, anyone want to try roleplaying faction leaders and generals?

I've done Gaul before. I can finish off Rome in my reign. (kill or severely cripple Julli and Scipii, eliminating the Senate).
