Turn 0 -- 1700AD - Hmm. Are we ready to declare I pondered looking around? Hmm not really, we need a bit more setup I think..

Oh.. there's the stack.. and it's a beauty. I guess we are ready to declare!

I ask politely FDR for his last 190g and he gives it to us. I then pay him 70 of it back to get his map and check that he hasn't gone and founded any more cities whilst we were distracted. He hasn't.
I move the workers back from the fog in anticipation of war with FDR so he can't steal them. Not that he'd have them for very long.
I head our stacks straight for LA, Portland & St Louis.
Turn 1 -- 1705AD - As anything completes in any city I will build military next. Not much use for anything else now is there?
I take St.Louis and Raze it.
I take Portland and Raze it.
Turn 2 -- 1710AD - I take LA and Raze it.
Turn 3 -- 1715AD - I take Miami and it's Auto-Razed.
Turn 4 -- 1720AD - I take Phily and Raze it.
Turn 5 -- 1725AD - Research set to Steam Power. No cities this turn

.
Turn 6 -- 1730AD - I take Boston and Keep it. We need somewhere to stage for the next push.
Turn 7 -- 1735AD - I take Seattle and Raze it. Calixtahuaca is taken and kept. Need somwhere to R&R for the Southern forces too.
Turn 8 -- 1740AD - No action... Just moving troops over the large cultural areas. The conq's can't do the job without some cannon support so they have to move forward one square at a time.
Turn 9 -- 1745AD - Some action takes place but no cities are captured.
Turn 10 -- 1750AD - And the last city I will take in this game, Atlanta is taken and I kept it for an outpost up on the Northern islands near our capital.
At this point, FDR has 5 cities left. New York can be sieged and probably taken on the next turn. Washington has a small force outside it's walls which can start bombarding on the next turn. A force at San Francisco will be there in the next turn and should be enough to deal with it pretty quick.
The SF force can then move on to help at Washington and the combined forces can move onto Chicago. I would raze SF and keep Washington. The NY forces can combine and move onto Houston.
I expect it will only take 6 - 8 turns.
FDR's taken a fair hit already.
Ralph's up to finish the game.
The save.
