I wish to make a point about the value of unconnected cities in Feudalism. I notice that since I am on an island, and want to prevent civs from landing on my island, that I can put any unit on the edge of my island and prevent the AI civs from landing. However, the cheapest unit to build for my connected cities are workers, and I lose one population for those. The cheapest non-worker or settler unit is longbowman, which takes many turns to make or 2 people in forced labour to make. However for unconnected cities, I can make units in fewer turns, so if I dedicate a city near a food resource to making warriors and pikemen, then I can create one every 3 or 4 turns and substitute those warrior units for the worker units or strong musketman units I am currently forced to use.
