I am not a a fan to build citizen house but an addict on making an army. My last option is to use the citizen pacification summon. Actually there are three choices in citizen pacification on War 2.
Relief will consume ***** food; morale will increase by 5; complaints will decrease by 15.
Charity will consume ***** gold; morale will increase by 15; complaints will decrease by 5.
Summon will consume ***** food; Your population will increase by ***** but will not exceed the population cap.
Another nice thing about summon, citizen will not fled from your city. I experienced my citizen walking away from my city due to too much idle worker.
