Total war: North and south next title?

[Liberator]

The difference being that the Japanese factions were warring amongst themselves. I don't see the states (apart from the North-South divide).

Agreed.

As we already had the creation of imperial Japan, I would like to see the wars that lead to the creations of 'imperial' Italy and Germany in the 19th century out of several smaller states, with final battles against the french and austrian oppressors
