What I mean is do the City-States type bonuses (Extra Food, Religion, Culture, Special Luxuries, etc) remain with the city when captured.
So if I capture a Faith-based City-State with I gain the +2 Faith per turn the City-State had or are those Owner specific and not City specific?
Another Example: If I capture a City-State with porcelain, will I keep the porcelain once it's my city?
