1) Why does it matter how far away a city is from your capital? and does the distance between a regular city and another matter to? 2)I noticed sometimes a tile is added up to a certain city without me buying it. is it because the city grew(food->improvement of the city) and does the game add a certain tile randomly? 3)Didn't really get the whole resources system". do some tiles "produce production", others food, others gold, and others luxury resources? do the improvement constructed by the workers on each tile simply make the resource related to the tile grow/be generated/collected faster? and I didn't get the whole focusing option. doesn't the "citizens" work all the tiles around the city? 4)How exactly do monuments, rivers, and other stuff I didn't noticed affect a city if it's built next to it?
