Instead of capturing enemy soldiers and turn them into slaves, why don't implement it on other ways? My concept of slavery and its consequences: 1. All houses, civic center, temple, barracks, marketplace and fortress have a certain amount of slave value, if a player destroy an enemy's house, civic center, marketplace, temple, barracks and fortress the player's marketplace will have an increase of slave and if the enemy have done the same thing on the player's territory and the enemy's market will have an increase of slave. 2. Slave value for houses, civic center and fortress are fixed, while a marketplace have the ability to generate slave value but with a very slow rate which means player have to conduct slave raid to increase its slave value. 3. There are different slaves for all building who have slave value, for example: houses have only female slaves, civic center have a certain amount of male and female slaves. While the fortress, temple and barracks have male slaves only or a large portion of male slaves. 4. Male slaves was able to build military and civilian structure and with a good gathering rate but a bit expensive, female slave have a cheap value but only able to build civilian structure and they have an average gathering rate on wood, metal and stone. 5. Slaves are property but still it was treated like population, 1 slave requires half of an average population regardless if they are male or female. 6. Slaves are prone to rumor, bribe and sedition which makes them very dangerous to human player and computer, player or computer player could exploit such weakness to win a war. 7. A rebellious slave have the ability to persuade his or her own kind to join the rebellion. 8. The ability to persuade could turn a group of enemy slaves into player's unit instantaneously this able a rebellion to spread like wildfire.
