When making timelapses of Fallout in the future, zoom into the North-East region, because otherwise nobody can see what's going on in there. It's also not like you're going to cover up anything important since it is surrounded by empty land.
In my playthrough, i unified Italy as Two Sicilies by March of 1938 and utilizing numerical superiority and Technological superiority, i smashed right through The North.
And here I thought they wouldn't join the axis since they got all the land they wanted, until they switch that is. How come? Change in popularity? A coup?
They ended the time lapse early, before Russia could unify. Which explains why the Oil Crisis, which usually starts in the 70s, didn't happen here. Also they forced India to conquer Afghanistan and Japan to conquer Western China, which never happens in base TNO. Weird...
