well the roman republic rules all of Rome (but only owns the city of Rome) and they tell me who they like and or hate then send me off to do something like blockade a port or capture a city, and then reward me with powerful units of events like games to make the people happy.
yes they were like little bugs that swarm one big thing to kill it, i had them from a city without a gov i left on auto recruit and didn't want to waste them.... so i killed them all =D
