More than a dozen feels like too many to have to deal with. The increased need for thinking, regarding city-planning and District placement, uses up a lot of brain resources, so I prefer not to have too many cities. With the building of districts on the map, it seems like they are representational, rather than literal, depictions of the world, which I think suits a smaller board-game style map with a quicker game pace. Normal map size, Standard speed feels to me like a Large map with slow speed. I currently consider Small map size, Quick game speed as the game's standard settings.
