1) To start, a leader is always a reason to consult team. This time army might have been most logic, but next one should be used for FP.
2) We don't need to keep units in Indian and Japanese cities for flip risk as they are gone they can't flip back unless they got a settler on a ship, but then we should still be able to contact them. Teno needs 8 units, but has tiny flip chanc without them.
3) We are still strong compared to Portugal so they still seem good target for now. We should be able to take them with the units we got now, but that will take lot of shipping. Still I think best idea, then come back to claim last Aztec city.
4) On science we should run straight for Theory of grafity, then see if we want some more, but we will most likely be able to trde for most other techs. Still don't want to go towards Shakes as it's 4 techs we don't need, the ai will research banking for us while we take magnetism. Do we want to give away uni's? It will speed up things. In IA we need Sanitation and Electricity asap.
5) After we take Portugal and last Aztec city we should take some time to improve our cities and land. Unless we get another leader then we should go after Egypt to build our FP. If we go there we should take both cities before building the FP, as otherwise we'll have a big flip risk and risk losing the FP for all times.
6) Did some quick counting on science if we get all cities we got now + Portugal and Teo, to max size with lib and uni and get the scientific wonders we should get some 600 science, not nearly enough to get 4 turn research. If we take Maya, Inca, Rome and Egypt with FP in Thebes we should be able to get 1000, but that's still a long way.
7) We now have 7 archer upgrading those will cost 420 gold, we could use the rest to get embassies. Make sure to get friends, we can sign lot of RoP's as the ai won't be able to take our cities by landings. That would include all scientific civs and civ we won't conquer (further away than Inca).
8) Before Niftan plays we should decide wether to war now or build empire, I would say take at least Portugal now they are weak they will grow stronger.
9) Niftan, Osaka needs some mm to grow in 4.
