The first is Civilization IV. This game takes you from humanity's humble beginnings in settlements and villages to the dawn of the space age. One way to greatly improve how you do in the game is to make the most efficient cities in terms of health, population density, etc.

The second is Spore. This game is a simulation of evolution, from the start of the game when you are but a cell in a vast pool of other cells and creatures who find you to be a delicious snack, to the end when you enter a galactic space-faring civilization. There are certain elements of the game which focus specifically on the building of villages and cities. This game was designed by Will Wright, the designer of the highly popular SimCity and Sims video games.
