As it seems up to me to take the next step, here I go.
The plan is to clear as many of the cities on the main beta continent as possible. With that in mind, I want to get as many cossacks as I can over there. My focus will be to max our gold and use that gold to rush units. I'm going to shut down our research (maybe do the lone beaker thing). I also plan to get into war with all the remaining civs. I know this means breaking the German deal but such is life. We don't need a rep and it ought to speed up the win that is a foregone conclusion.
1050AD T00
Step 1: Cycle through our empire and change builds and citizen allocation
After about an hour I changed a lot of citizens, changed settler builds to workers so as not to waste too many shields, changed almost all the gallion and frigate builds and MMed for food in corrupt cities. I don't know who did it but when a city has waste such that it is only producing 1 shield, there is no reson to mine anything around it. All the squares should be irrigated so that it can support specialists. Mines are just a waste of land and worker moves.
Stept 2: Drop science to 0% now +554gpt after some harbour rushes
Step 3: Declare war on Germany
Take two of the slaves working near Berlin. Move the stack of cannon into Kraut lands. Gather the cossacks on our continent and send them to our dispach point.
IBT Some skirmishes between our rivals. I wasn't aware they were all at war (I guess I should have checked the diplomacy screen)
1060AD T1
Finished the build changes and put most of the cities on wealth
Razed a Roman city in the north
THEN all the workers started moving all over the place. What the H#$& is goign on? They are on automate! Please, please, please please, please NEVER do that again. The workers that were going to focus on railroading our attack route and giving water to the cities we have on the beta continent just wasted all their moves. There were even workers on our original continent moving to tundra to do something. No wonder the improvements in our empire are a mess.
Raze the Roman city near New Berlin, move the rest of the cossacks to new berlin
Make a new army and move it towards the railroad
Raze the German city N of Sttugart
We have more than enough forces on the beta continent to win in the next 20 turns. I don't think I'll be able to do it but hopefully I'll clear the continent (maby not but most of it at least)
IBT Zzzzz
1070AD T2
Raze Leipzig
Finish loading an army and move it towards Berlin
Raze New Berlin(another island cleared)
Raze Washington
Raze Baltimore
Raze Heidlburg
Keep RRoading towards enemy cities on the beta continent
Found a bunch of cities to get rid of the settlers (we are at +567gpt now at least)
Start sending some gallions to the straights between the continent and the last populated island
IBT Nada
1080AD T3
Raze Miami
Keep railing and moving troops towards enemy cities. The cannon stacks are ridiculously slow so I decide to start sending them over to the small eastern island. Maybe the'll get there in 3 turns or so. Enough time to take out a city or 2 before the end of my set.
I set all the newly built cities to wealth. Partly for the coin (that we don't really need and partly bacause I can't be arsed to manage them

+607gpt
Rush some harbours and cossacks
IBT The yanks take out 2 cossacks with a couple MI. I guess cossacks really don't defend well
1090AD T4
Raze Salsburg
Take Berlin just because Nikita Khrushchev wanted it so badly (dumb though as now I have to manage it)
Raze Frankfurt
Raze Detroit
Both the Americans and Germans are down to 3 cities each on the beta continent. See, we were ready for war
IBT
1100AD T5
Raze Hamburg
Raze Konisburg
Raze Munich and the Germans are off the main continent
Take Philedepphia so we can get Sun Tzu's and our units can heal faster
Raze Buffalo
American only have Huston left and I'm heading to the Eastern Island
IBT Zzzz
1110AD T6
The Americans are no more as Huston falls
Raze Bonn on the Island
Raise the lux slider as we have plenty of cash and we don't need any more units
IBT lots of we love the Czarina day and Mecca riots
1120AD T7
Raze a German city but I forget the name. Both the Germans and the Romans are down to 1 city each
IBT The Germans settle a city (I guess all they had was a settler)
1130AD T8
Raze the last German and Roman city and that seems to be it
Thanks everyone. I learned a lot for the game. A special thanks to Sal for pointing out the ins and outs of a settler pump and Buce for the military eye. I've included the save just befor the game wins if you want to check it out.
The last city
