I've played about 80-90% of the leaders and I have achieved every type of victory at least twice now and I've noticed something about the various leader traits. In my mind they seem to group like so Group 1 -Industrious -Financial -Philosophical Group 2 -Creative -Expansive -Organized Group 3 -Aggressive -Spiritual Now, at first I thought that Elizabeth and Qin Shi Huang were going to be the most powerful leaders by far since I thought that the Industrious, Financial, and Philosophical traits were the most versitile and most powerful traits, however I noticed that leaders that have a mix of group 1 and group 2 traits do just as well. I've also noticed that overall, a leader with two group 2 traits is really pretty terrible. Overall, this is how I would rank the various combinations of traits: Group 1 & Group 1 - Good Group 1 & Group 2 - Good Group 1 & Group 3 - Okay Group 2 & Group 2 - Poor Group 2 & Group 3 - Poor Group 3 & Group 3 - Poor I've found that the only way this analysis can be flipped on it's head is if you are playing a warmongering game, but I'm big on versitility and it seems like the only hope those groups have that I've rated poor is to go the path of heavy war. Recently I've taken to only playing leaders that have one group 1 trait, but by that same token I've picked opponents that have at least one group 1 trait since opponents without the group 1 trait seem too easy to beat. I would like to see comments on this.
