I got an idea for something new for galciv 2, This is an idea but like Civ 4's new expansion coming out how about corporations that each race can have , ( pre made for pre made races) and for custom races you can make your custom one, and they have a name, leader, and you decide what extra bonuses they have which help boost either economy, military, research or social.
They also let you have a certain item that you can choose to an extra bonuse such as diplomatic translators have a better bonuse
