Civilize Yourself With Ideologies
This is to make cultural victory a viable and interesting option. Policies are already in-game, but now they have been expanded, somewhat remixed and got two now friends - Aesthetics and Exploration.
And once you hit the modern era and build three factories, you'll get to choose from three Ideologies - Freedom, Autocracy or Order. Seems a bit simplistic, but this is par with the simplistic course that Civ V has taken. Anyway, these new ideologies have their own wonders and special diplomatic and hopefully military boons.
Can you wait for July 12 to find out what they are?
