The world is round. England is also in the region 12-15 tiles away from Paris.
For the far future, lets estimate what things could be worth for us in science.
Cities fully developed, size 12 with lib+uni
-Our 5 city core: 220.
-Paris with FP: 75
-Wonders in Paris: 75
-Wonders in capital: 55
-Thebes: 55
-Delhi: 40
-Chichen Itza: 30
-Persepolis: 30
Around France with second core setup
Orleans: 40
Bergen: 40
Viking 2: 25
Scientist farms
-Memphis, India 2, Spain cities, maybe inca and very remote cities to be used as scientists farms. Such towns could support about 5 scientists for 15 cpt
Useless
Copan Edrine are Mostly useless. Bad commerce, bad development and no food for scientists.
Istanbul, Rotterdam, babylonian cities, Mongol cities, Tarsus all seem deprived of fresh water or have otherwise are not good to support scientists.
These towns can all support only 2 or 3 scientists max.
Developing cities
Bergen and Chichen Itza will be hard to develop. They need aquaducts and have moderate production only.
Thebes may be moderately hard to develop. No fresh water for growth.
Delhi and Persepolis will be easier to develop.
Paris obviously is devolped in like 5 turns.
Orleans could get help from Paris.
Conclusions
Thebes and Delhi should be developed and will be an addition to our core.
Both the second core around Paris, and conquering the science farms are only moderately usefull. This strenghtens my preference to build up our core quickly.
Paris is a really important part of our total Potential. It should together with Memphis and Delhi, be a primary target. Since we can take Memphis and Delhi any day we'd like to, i think Paris now really should have priority if we think the risk is not too great. If don't take it now, it may well be IA before we can.
The second core around Paris would be worth a total of little more than 100 science. probably around 20 if we just use it for scientists.
Developing a second core around Paris is worth about 80 science.
The choise is between developing a second core for 80 science and conquering science farms. I think we will end up going for the science farms. Oreans however could be of great help for us while we still have to conquer these farms. It could produce mass units and not bother building a university since after taking the farms, it's corruption will go up anyway. This is a future issue though.
For now, i think we should take Paris, then Thebes and Delhi.
Meanwhile, we want to develop our core. Developing our core would take 15 turns of producing workers before we join them.
If we do this before conquering Thebes and Delhi, it would delay the conquest of those cities by about 15 turns. That would cost us like 1500 science if development also is 15 turns delayed (less than that is likely though since the cities can also grow a little under enemy command, and maybe even build an aquaduct, also 15 turns later, we will have a more powerfull nation to help the cities with workers)
The benefit developing our core faster with worker joins i estimate, based on the graphs i posted before, on at least 3000 science.
The conquest of science farms should not really be bothered by the fast core development. After this development, the 4 new towns are ready to make units earlier and faster to make up for the delay of those early units.
Conclusion from conclusions
Therefore, i think we should take paris, then develop our core, then take Thebes and Delhi.
We should now produce 1 more MDI, 3 more dromons and sail to Paris.
Then, we have a completely undefended core. The large island can defended by the AC's that are produced there.
Our capital could build 2 MDI before going into worker production mode. Delaying our core upgrade, these are extremely expensive MDI though. So please don't suggest to build more
, rather, we may build them in Kyoto instead...
Teno: Lib - Aqua
Teoti: Worker - Aqua - Lib
Osaka: Harbor - Aqua - Lib
That would mean we will start building workers in about T10 and stop producing in T25-T28.
That provides about 120 worker turns. About to 200 together with the worker from Teoti and the slaves. With those damn aztecs destroying our improvements, we roughly need:
Teno: 8M+8R = 80
Kyoto: 8M+2R = 55
Osaka: 2jC+5M+4R = 90
Teoti: 2fC+2M+2R = 30
Total: 255
That's pretty close, let the workers work 3-4 more turns and join them at T30 should fit well. The aquas are then also ready.
7 well developed size 12 cities 30 turns from now. Doesn't sound too bad does it ?
(only missing some Unis as we wont have Education)
