A nice addition to DoC might be city-states; i.e. civs consisting of one city and not much land. Surplus health counts as food. This encourages lots of trading/vassalizing. Land only comes under its control if it has 97% of its culture. For water, 90% is enough. Question: should these be created randomly, or should they be specific civs (Venice, Hong Kong, Singapore)? Should they be playable? Apologies if this has been discussed before.
