I am probably the only one who picked my trait combo, so I'll explain why. Seafaring and Commericial (yep, the English), because the two of those together will allow you to be the commercial giant, with the advantage much more pronounced at the end (metros and half priced commercial docks). But having huge amounts of gpt is so much more satisfying to me than a good warmongerer or quick expander. So even though I would probably choose the Inca to test out the next higher level, playing as the English is just so much fun. And I have never even once used their UU.
