I don't know if this is feasible, but I would like to be able to select civs that you can currently only choose to play as when they spawn in-game in the normal selection screen. For instance, if I want to play as Italy I have to play another civ until they appear. I would like to be able to just choose them from the start. I am guessing that the problem is that if Rome never collapsed then Italy would never spawn. This could be fixed by having a fixed time when they spawn if the player chooses to play as them but not when they are AI controlled.
