I was playing as Songhua today and Hanoi gifted me a Cho-Ku-Nu. I didn't realize until I attacked a barbarian with it a few turns later and realized I had another attack. Getting UUs from militaristic city states makes befriending them a little more worthwhile for me. Anybody else get UUs from a militaristic city state? Does each city state have access to it's own UU or is it just random?
