Tabarnak, I wanted to thank you for this walkthrough even though I have difficulty with it. I did learn a lot and I think it will help in my future games.
So much so I'm thinking of developing a different, but very similar, 3 city strategy that might not be as aggressive, but will let you develop with stronger units a few years down. This will be for those who play on intermediate difficulty, say around Emperor (or lower).
I'll post more once I have it worked out. It already works fine on King. Need to tweak it with what I've learned here.
Thanks again to everyone. This forum rocks!
