All this talk about ACW and how it should be represented in the game is quite silly, because the game will have its own dynamics. The ACW, WWI, the Crimean War, German and Italian Unification are all nothing more than possibilities. Not history dictates, the player does. Maybe ACW will begin in 1850 or in 1878 or won't happen at all if the US player acts in the right way. Maybe CSA will consist of more or less states, technologies might be more advanced or rudimentary compared to the real ACW. Maybe the British intervene. The possibilities are endless. This goes for any war fought in the time frame chosen for Victoria.
I don't wanna play Russia and know there will be a Crimean War, a war against the Ottomans in 1877 and a WWI which will see a Communist Revolution. I want to have the right to make my country crash already in 1836 due to very poor decision making or make it a serious competitor of Britain in the quest for power and glory. The only date on which everything should be historically correct, is 1835. After that, I'll take over myself.
