What do you miss from Civ 4 and Civ 5 that are not in Civ 6? There are many missing nice things that were in previous civs. This thread is mainly to talk about the things that should be added back in. I miss the vassalage system from Civ 4 and the world congress from Civ 5 the most out of all of the features. I also would like there to be a map size equal to Civ 5's huge.
