This is the updated city build thread as of 510AD.
This first map is of the far west end of the continent. Sites A, B, and C can all be built if we're willing to use tight spacing there. I think this is a good idea because the FP and Palace are both far away, so these will be high corruption cities anyway. There will be a practical limit to their productive size until we reach Democracy. The tile marked BLOCK POINT 1 is critical to hold with a unit, because it is not covered until the 2nd border expansion, and does not make a good city site because it overlaps on all land tiles.
Edit: as of 610AD, sites A and C have been built.
