Base terrainEdit

Base terrain worked by a city citizen will provide up to 2 basic resources (food, production, gold).  The resource yield of terrain can be modified through buildings, technologies, or worker improvements.

The effectiveness and mobility of combat units is affected by the type of terrain they occupy. Mobility is improved on tiles with Roads or Railroads.
