I was playing crusader kings 2 and was thinking it would be kind of nice if the citizens in gal civ 3 could develop traits. for example a Drengin citizen develops an appetite for eating rodents and would gain a bonus to food production if we declare war on the Snathi. or a Free Trandals female has fallen in love with the Terran Alliances Justin Beiber and wants you to raise diplomatic relations so they could be married, if successful citizen could gain a permanent diplomatic bonus with terran alliance or if failed could get a morale penalty. anyway it's probably to late to include this but I thought that something like this would add more personality and humor  to the individual citizens themselves
