Ok, I have read the other posts and thought it is about time I weighed in. I play with Elizabeth about 1/3 of the time. She is my most bestest leader. First to clear up some things.
A. Research times for the human player are determined by game speed not difficulty level.
B. Elizabeth with her financial trait combined with seafood resources starts much faster than Churchill. Later in the game his protective/charasmatic traits make awesome Redcoats. But even Liz's generic redcoats are awesome since she gets them way sooner with her finacial trait for research and her Philo trait for for academies/settled Gs and bulbing.
C. the great lighthouse is only good if you plan on a lot of coastal cities.
Now to the mega Liz seafood strat.
step one. Research BW while building a workboat. On epic speed it takes 23 turns to tech BW and 12 turns to build a workboat working a forested plains hill.
On turn 12 launch boat and work the clams/crabs and start building a warrior. as soon as you reach population2 switch to a worker. working the seafood and the forested plains hills
Turn 20 you discover BW(sooner because of the 3

from the clams/crabs and switch to slavery. Start researching hunting.
On turn 27 start researching archery.
On turn 30 whip your worker out. Move him to a forest while you finish building the warrior.
On turn 33 start building a barracks.
On turn 35 move your worker to a new forest. and start chopping...this is before the first forest is completed.
On Turn 36 switch build to an archer and start researching the wheel to connect any copper you may be headed to get.
Turn 39 you are pop2 again and switch to building a settler. Working the seafood and the plains hills.
Turn41 finish chopping then move back to the first forest.
On turn 43 you finish chopping and move to a third forest. And start researching mysticism for the first cities border pop
Turn 48 whip your settler. Leave him in the city.
Turn 50 you complete the third chop and you have your archer.
Move your archer and settler to the new city of your choice. You have 4 turns until mysticism and are 6 turns from pop2 again.
Ok, in 50 turns we have a warrior/archerworker and a workboat built. And the following techs. BW-hunting-archery-the wheel and 4 turns from Myst.
By your method on turn 50 you have your second city founded for 6 turns but are 3 turns from completing the wheel, 3 turns from pop2 and have no military. Assuming a lion didn't eat your settler. You are behind one full tech and 2 units. Plus you wasted one more forest than I did. And still haven't switched to slavery. With Liz my tech lead will continue to grow. And it's even scarier if there are two seafood resources in my BFC. i switch the first worker for a workboat and am way ahead of you. The archer finishes on turn 55 and i am done myst and 4 turns from masonry.
If the seafood is a coastal fish. Get the settler on turn 42 and have only used TWO forests. I can use warrior #1 to escort him
