Unrestricted leaders, yes, and random civ. The Financial Trait, IMHO, is the most powerful trait in the game. After that, allot depends on what you want to do. For example, if you love wonders, then go Industrious, if you love hyper expansion, then either Imperialistic or Organized should be your second choice. If you love going to war, or if you feel that you'll be at war allot, then Charismatic, Aggressive, and to a lesser extent Imperialistic should be your choice. If you're going for Culture or a more peaceful approach, then Creative would be your next choice, however, for a real Culture victory approach, Industrious should rank higher. Finally, if racing up the tech tree is your goal or a space race then you should lean on being Philosophical or again...Industrious for some key wonders, like Colossus, the Great Lighthouse, the Great Library, and Pyramids.
In all of my games, these wonders have come out on top over and over again in terms of accelerating my research rate. All the others are nice to haves in my opinion and building the other wonders factors in more as a wonder hording strategy to weaken the potential growth of other civs.
With the above in mind, I'm leaning toward Organized, Creative, or Industrious for secondary traits. That being said, the following leaders come to mind:
Huayna Capac Financial, Industrious
Willem Van Oranje Financial, Creative
Darius I Financial, Organized
However, I can definitely see a strong case for Mansa Musa Financial, Spiritual, especially since this is a demo game, and I can potentially see many civic changes in our future.
By the way, my character will also spend time at the pub, where much of my historical writings regarding our nation's heroic events will take place.
