Well, I played 11 turns to end up in 1750ad actually, I hope it does not bother anyone... Anyway, next player will surely get the victory message ! Can we see somewhere in the game how much of the total land we have ?
pre-turn (last Aggie's turn) : The 1st artillery shot against Marseilles is heard and the Aztecs declare war on us (MPP) !
Almost all our artillery is on the other continent, so I decide for a blietzkrieg ; the French don't have oil anyway.
Marseilles (size 10) razed after losing a few tanks.
Ditto with Chartres (size 12).
IT : The Aztecs fail to attack us.
The French bombards us, and I'm afraid they have tanks and they use them to destroy some cavalries (been too ambitious last turn).
1- 1700ad : Rheims (size 12->9) razed with tanks.
Humm, I've just noticed a source of oil in the French territory, my bad...
IT : The French make a maritime launch near Sevastopol : 11 infantry + 1 cavalry + 1 tank !!
War weariness begins to strike : lux at 20%.
2- 1705ad : The great artillery strike against Tenochtitlan (size 12) begins... After 23 strikes, the city goes back to town status. A tank army takes position on the nearby mountain.
The French SoD is almost destroyed (1 cav + 1 injured infantry).
IT : Feeble Aztec and French attacks.
3- 1710ad : Aztec salpeter source destroyed.
Tenochtitlan razed.
All French troops removed from our territory.
IT : French bombardments.
4- 1715ad : We pillage a French rubber source.
IT : French bombardments and counter-attack.
5- 1720ad : Lyons (size 12) razed by tanks, 5 bombard planes destroyed.
Orleans bombardment : size 18 -> 14.
IT : Injured tanks destroyed by French tanks.
6- 1725ad : In fear of war weariness, lux at 30%.
French oil source pillaged.
Orleans bombardment : size 12.
We pillage a French horse source.
Still in fear of the French culture, we raze Paris (size 12) with tanks. The French culture is huge !!!
IT : Feeble French counter-attack.
7- 1730ad : Teotihuacan razed.
Besancon razed along with Newton's.
IT : French reinforcements arrive from their island.
8- 1735ad : Orleans now size 1.
Xochicalco now size 5.
Tlaxcala captured with an infantry army !
IT : Feeble Aztec and French counter-attacks.
War weariness increase.
9- 1740ad : Orleans (Shakespeare) captured with tanks.
Xochicalco captured with a tank army.
Heidelburg captured.
Sverdlovsk captured.
IT : Light French bombardments.
10- 1745ad : Beginning a fill-up-the-open-territory program ; first settlers built.
Hyderabad founded on an "ancient site".
Bengal founded on an ancient site.
Chittagong founded on an ancient site.
IT : Ditto...
11- 1750ad : Avignon back to size 10, so attack... Avignon captured.
Tours captured. The French have no city left on OUR continent.
Punjab founded on an ancient site.
Dacca founded on an ancient site.
Indus founded on an ancient site.
A suicide infantry attack makes us win Tlatelolco (size 1).
OK : settlers don't airlift, so you'll have to board some on a boat next turn, direction : ex-Aztec territory.
We now have a lot of tanks that can be boarded on the boats, via Hadretum, direction : the French island ! Remember to keep one boat for the settlers !
We still have some Aztec cities to capture, so making peace with Joan now won't stop war weariness. So I suggest we capture the French island (2 cities) straight away.
the save : 1750ad
WE ARE ALMOST VICTORIOUS !!!

Really crazy that we could have caught up the AIs with just 1 city in the beginning. But it was an Emperor game, and there was not much land, so that made it easier.
