Food feeds the many citizens of your cities, but luxury comes at a price, as it is also grown by them too. When a city is built, some surrounding tiles will have little apple icons on them showing the areas of which food can be grown. Certain buildings (Aqueducts, Harbors and Granaries) can boost the production of food in these tiles from 1 food per tile to as much as 3 or 4 food production on every food tile!
Food is produced every turn and automatically feeds the many citizens of your cities. More and more citizens arrive after a population growth every 9 or 10 turns. Population growths occur fairly regularly at the beginning of the game but start to become less frequent towards the Medieval Era. Houses will automatically appear as will citizens at the beginning of the game and will continue to appear or upgrade as the course of time is followed.
Growing food is much more simple in this installment of the Civilization series than in some others such as CivWorld. Food is automatically grown and dispersed to the citizens of your city and still doesn't cost you a penny. But free food is not really the correct approach:
Food is automatically grown and does not reduce your gold balance but it does require certain buildings to produce enough food to feed an ever-growing city.
(In a simpler way...)
- Food contributes to population growths.
- When food tiles are not being upgraded with the use of certain buildings, the population will only add a few citizens on the next population growth.
Food tiles (although the visual aspect of Civilization Revolution does not consist of tiles but of just land) are essentially just the areas inside your cities radius which can produce food for your city. Other tiles in a city consist of:
- Food (apple icon)
- Production (hammer icon)
- Science (laboratory test tube icon)
- Gold (gold bar icon)
