@Broken-Mortar Absolutely. I mean, think about it. You’d have to have contingencies for any situation. What if the USA is conquered in an 1885 game? How do you set up and play the 1914 game? Does that affect the balance?
Likewise, what if, say, Germany and France were both defeated in a 1885 game? Do the alliances get shifted based on who survived?
Another big one would be a 1914 scenario where there’s no Russian Revolution, or at least not a successful one. That rewrites a 1936 game entirely. There wouldn’t be a Comintern power at all, and presumably no CCP or Republican Spanish either.
You’d have to have predetermined setups for the next game, based on how the last one ended. If Germany loses this is their set up; if Germany wins this is their set up; if the USA loses this is their set up; if the USA wins this is their set up, etc. etc.
It would be impressive, though I’m not sure how feasible the work actually is!
