Oh right, MAM is out of town, looks like its me. You can delete that sign from the strategy layer.
Here we go:
Turn 0: 1420 Uneventful.
Turn 1: 1425 Our caravel spots the Maya land and we get invaders. Tikal is split off from the rest of their area by Jungle, so I donate most of our troops, and open borders. Vassalization by capitulation is not an option, so we'll have to butter them up to make them do it willingly. One of our knights spies an Incan scout, and we get invaders to them. This time I declare war in an effort to get capitulation.
Turn 2: 1430 Finish gunpowder. Start civil service. Drop research to 60% to keep a positive cash flow.
Turn 3: 1435 I start an amphitheater in Lyons. Not sure if we should focus on something else for this one, but happiness is going to help our stability, which is likely going to start taking a hit soon. Indias lose Mumbai to the natives.
Turn 4: 1440 Start ampitheater in Orleans. Move our artillery and some troops into Portugeuse lands to start bombardment.
Turn 5: 1445 Start bombardment on Lisboa. No casualties on our side yet. Settle a general in Paris.
Turn 6: 1450 Germany finishes the Leaning Tower. Start courthouse in Paris. Take Lisboa. Start courthouse in Lisboa.
Turn 7: 1455 Maya offers themselves up as vassals. We accept naturally. Buy Maya's map for 30 gold, trade theology + 35 gold for civil service from Maya. Start worker in Marseilles. Viking revolt occurs in Birka. Set research to education.
Turn 8: 1460 Looks like the Incas lost a city to barbarians or natives. They have only 3 left in their capitol, so they should capitulate after we take out 2 of those. This map lacks a NW passage, and I still haven't found the Aztec after exploring the east coast of N. America.
Turn 9: 1465 Whip library in Birka.
Turn 10: 1470 Inca collapse

. If Aztec are around in this game, we'll want them as vassals. Otherwise we can try for the Americans when they spawn. Start bank in Lyons.
On Portugal: They were wimps against our cannon. Very good prep work all around.
On declaring war on Inca: I like to get capitulation out of the Amerindians and have a high success rate at doing this, as opposed to waiting for them to willingly vassalize. Plus it guarantees they don't go to someone else. We still have the Maya who are very close, and we don't really need a second vassal in S. America. If we can get Aztec or America for N. America, that would be ideal. Besides, it looked like the Incas were about to be overrun by barbs/natives soon anyways. Their military was mostly melee units.
Our troop surplus: We could focus on happiness or try to take some more Viking lands.
Future directions: Beeline for Liberalism. Don't trade the techs leading to it.
Probably donate some techs to the Maya, and once we take the remnants of the Incan lands, give those cities to the Maya.
Settle a city near those roman ones with Paris's settler, and settle the GA there. I sent a worker to stat building a road in that direction. I'm thinking on the grassland in between those 3 resources.
We have lots of time to circumnavigate, so use the caravel in the south to look for Aztecs and then Asian civilizations. Use the one in the North to finish the circumnavigation.
Maax is next?
