First what are your own thoughts about our war situation, techpath, diplo, city and worker management and so on?
War: have you looked at the save? I left a stack 3S of St.pete, which I think should go take it. The army near Moscow could head towards Novgorod, the shrine city, and heal while bombarding (1-2 turns) since we have the medic general Talvela there.
I don't guarantee that my notes on enemy garrisons are 100% right, they may have moved the units back and forth. Whatch out for Chichen itza, Stalin has some troops in Yekaterinburg so keep an eye for them. Northern cities are the best land so prioritize them, capture the southern cities after them.
We'll get our GS in 4 turns if the scientists aren't fired, I'd wait until that before starting to run 100% science. Idk if it's better to start cs before that to get more food from additional farms sooner, it's basically beakers vs food (if teching cs).
When Feudalism comes available for trade try to get it (not for any price if they want gold don't give it, instead tech feud partially to get a discount).
I would give Lakamha's corn to the beaver city to start whipping there since Lakamha isn't a good whipping site, it needs to work cottages and has higher pop. Beaver city has lower pop, which means better conversion rates for whipping.
Teches: this depends on the long term plan. Get engineering for early mil victory as suggested earlier meaning mc-mach-eng route? I think this is doable. Or tech further towards lib? In both cases CS is ok tech giving access to maces and irrigation.
We haven't yet decided how to end this war with Stalin. I perhas should have planned that when I started the war. The problem is that we can't know for sure when feudalism is available for trade and that means it's harder to decide whether to capitulate him or not. Stalins southern cities aren't good but with GLH the coastal ones are ok so taking them is ok option. I hope that you'd wait for some comments on JSS and Sampsa instead of giving the team a time limit for responding.
Last thing, how long are you going to play? Until a certain city has fallen?
Edit: if something unexpected or threatening happens on the front, feel free to stop and ask for help.
