What about adding in the game migrations and pollution? The first could be caused by differences of wealth (that are also indirectly linked with difference of technological level) or by a natural disaster and could obviuosly produce a displacement of population and a diffusion of the culture of the country of origin. Pollution, instead, could be produced by industries or other human activities such as trasports and could lead to seriuos consequeneces for the population, the environment and the economy, such as desertification or global warming. But it could be contrasted by new technologies and new "greener" plants. Contrasting pollution could be linked to the United Nations or other projects like the Kyoto Protocol and the nations that produce more pollution could be punished, instead the "greenest" nations could be rewarded.
Another thing is that I would like to play big maps without a very very long time to change turn (more than 2-3 minutes) and so I suggest to work on this and to allow Civilization 5 to use more than one processor in the same time.
