It seems, from the player's perspective, to be several minor uncoordinated factions, doesn't it?I said that it affects gameplay in ridiculously complicated and strange ways. Unit recruitment, army movement, economy balance, diplomacy etc. It is not broken or sth, but it doesn't function as a bunch of really independent states would; it's just how the engine works. AI manages the faction as an entirety, it doesn't schedule according to specific cities.
