Yes, and it worked nicely from a display perspective. Shame that it greatly increased maintenance due to some questionable coding, but useful for trolling the occasional turncast game without people realizing it . (In Civ IV, maintenance calculated one of its components based on distance from capital. However, this was a function of the maximum possible distance. On a flat map, the maximum possible distance on a map was from one corner to the opposite corner. On a round one, it was less, and on toroidal even less than that. With a shorter max distance, the proportion of a typical city distance to that smaller number is great, leading to more maintenance).
