Could someone sum up all the trait combos and post their advantages? Would be much appriciated.

It's actually explained in game; on the paper manual; on the .PDF manual provided with Civilization 4 games that didn't have the manual's included.

I won't answer this here; because if you don't have the .PDF manual; chances are you have a pirated version of the game, and it would be wrong of me to divulge information given the circumstances.

For paper manuals: It's page 159.

For .PDF manuals: click the "Civilzations" tab.

In game: Simply run your mouse over the flag beside the Mini-Map. It explains your trait bonuses.

...Or, chances are that we just don't have the game yet and would like to know about them. As is the case in my case.

yeah..I have it, i also have the pdf, which explains some, BUT. I would like to know how these cobos work in practise. If someone would :D
