Had a few questions on the "tile" concept, from about 100+ hours of playing mostly on Prince: 1) What is the maximum number of tiles out a city can potentially grow to? 2) What triggers a city to increase the number of tiles in their control? -What is the specific ratio for it based on food and based on "culture" gains? 3) How far away can a city work a tile grid? If you have a city around 30, does it make sense to build farms/lumber mills past X number of grids? 4) How does the tile acquistion work? I notice some tiles are not available earlier yet later the city grows well beyond...does it have a max of filling all tiles 1-2-3 away before going 4-5-6 and so fourth out? 5) Later in games, AI Civs keep telling me "Your recent expansion blah blah blah blah" (You know the line) even though I haven't actually bought a tile and in fact I have gotten notices saying "You kept your border promise." Is the AI taking it a step further and actually wanting me to check "avoid growth" on my cities to prevent even culture/food tile gains?
