I often hear the criticism, "you aren't overlapping your cities." I'm wondering if it is all that important. In the early game it does mean fewer worker turns for cities sharing tiles to have improved tiles available to work. Closer cities also require less distance maintenance. Still, I often watch playthroughs where overlapping isn't used by some of the best players. In the latter game, small cities with weak production may result when cities are closely placed. Also, why start a city right next to the capital and grab one resource when you can go another couple spaces away and grab three? Thoughts on this?
