Just had a look at the save and was disappointed in lack of use of scientists in our science farms.
These totally cirrupt cities should never work a 0 fpt tile (Thunderfall - coal mountain, Leptis Magna 2 unirrigated deserts, Hippo a mountain, spSeville gold moumtain and Almarikh coal mountain) We get no production nor commerce from these (ok, I think gold mountain may give 1 commerce) but these can easily be replaced by scientists for 3 science per turn. Similarly 1 fpt tiles should be fired and hire a scientist instead. Many RRiGrass tiles are not being worked whilst 1 or 2 fpt tiles are worked instead. In these corrupt areas only food counts. Excess food must then be used to hire scientists.
Currently civ assist shows us with 26 scientists. Quickly scrolling through F1 city screens and firing low food tile citizens and hiring scientists where food wasted I increased this to 89 scientists - I'm sure with some thought into switching tiles between cities this could be increased further.
The railroad around the mountain ring looks impressive, but I'm not sure what its supposed to achieve. Thats a lot of worker moves when we still have jungle above east choke to clear, irr and RR; jungle near Sabratha and above west choke, unirrigated grass in old Carthage; almost complete jungle on east jungle isle (edit - btw I notice the workers on the iron hill - we dont req more iron connected up and mining it will be wasted on corruption so why not clear the jungle first so we can hire more scientists); unimproved mountain tiles being worked (or waiting to be worked) by core cities (see Oslo); and plains tiles needing mining in core cities with wasted food (see Cop, Rey and Birka) to increase production.
I agree we have enough workers - just need them doing useful tasks. We need more settlers. Spain can support 13 more towns, eastern jungle isle 1 more as well as spare spots in food rich regions old Otto and old Carth.
I recommend switching many worker builds to settlers. Also I suggest switching T & WV to unis and growing (will give lots more science).
I remain unconvinced about iron works - due to be built in 31 turns - how much use will it be before we give it to Gandhi? My understanding is that small wonders disappear when the city changes hands. If we are going to build it then at least build it quickly by using coal tile -> 22 turns.
Notice a galleon with 2 settlers on board between east jungle isle and Celts - ? where is it headed - I suggest Spain.
Why is Farsund building lib?
ToE is now due in 12. Steel will take 3 more even with scientists, that leaves 9 turns for refining and combustion. Is this doable? Both these techs are same cost - presently can show 5 turns to refining with scientists added, might be pushing it to scrape a 4 turn tech (now there's a challenge for the next player

)
If we want to build Hoover then it would have to be FC in order for it to have river in its radius. Not sure if its worth it as not much left to build apart from SETI and that should be in FC anyway - has it time for both?
Obviously we should get Celts 105gpt to help fund our science push.
I favour also giving Celts lots of luxes to ensure he spends his commerce on either gpt to us or helping tech research.
We are approx 22 turns away from releasing Gandhi.
