I looks like we should head straight for TOE. The AI already have Med and Electricity - as well as Ironclads and industrialization.
I wouldn't be suprised if the AI has Infantry in the not to distant future.
On the plus side noone has started Universal Sufferage. Some civs may have mobilized. [Cannot build TOE if they have]
First I would have to see who has what. If they have Med and Elec, but not Communism nor Nat, nor Ind, they are not going to pass those up to get Sci Meth.
If they had most of those as well, then we have no chance anyway to beat them to ToE.
Second, if we time out a solid prebuild and get get Sci Meth in time, we are golden. It is rare for an Emperor AI at war all time time to pull off ToE.
Finally, I am not sure we will do better by delaying RP. Rails will let us make up some time in research with the ability to have more food and support more scientist.
Rails will help get units out and those factories up with the extra shields.
Not to mention the use of infantry will let us get more aggressive. No need to cover those slow move cats and the ability to send out worker parties under infantry. They can be used to cover damages units, instead of armies.
To cut off certain tiles and force units around them, instead of armies.
As to the workers, it is a double edged sword. I see merit in skimming them, but I do not like to do it in towns that are my production towns. Especially when I cannot afford the extra support.
I am ambivalent about it as it does help get the rails up, so I would not oppose it. I just do not do it myself. Now if I have the free support, then by all means I would do it.
