It seems like a lot of the happiness from the social policies has been moved to the tenants -- for example, the happiness from universities and walls and such. This seems to suggest that rationalism and honor have changed as well.
However, there is happiness in the exploration branch from harbors.
Aesthetics seems to have gotten some of piety's policies, so piety seems to have changed as well. So at the very least piety, rationalism, and honor seem to have some changes.
I'm having a little trouble seeing the benefit of cities starting with 2 population as well as the monument tenant once your ideology is set since it will be later in the game.
Do you think a lot of happiness produced from policies has been moved to later in the game to slow city sprawl?
