I am getting a bit tired of the square grid, and think that the map could be better portrayed as a hex grid. That way city and cultural radii will be (generally) circular, you don't have to worry about trying to fit a city into a jigsaw puzzle of competing city footprints. The only real difficulty will be that at city start, the footprint will be 7 tiles, as opposed to 9, and the full city footprint (after the first cultural expansion) would be 19 tiles, as opposed to 21. These differences could be easily offset by increasing the production in the center tile in 2 stages: One when the city is first settled, and the other when the first cultural expansion occurs.
