Once I got Dowed by England and Germany at the start, I realized I had to build up a potent defensive force. So I dedicated the capital to first max hammer output, and then military. Caravans were used to deliver hammers, GE rushed 2 factories (traded coal with France). Built a couple of Cavs and 2 Rifle Cannons before building HE and Mil Academy.
I also filled 3 left Social policies (before going to the right side ones) to maximize my army efficiency at killing invaders; it did not take long to complete the full SP tree). 45%(clear terrain)+15%(HE)+15%(in own territory)+15%(adjacent to friendlies)+15%(General) gives
105% bonus fighting in my territory, not to mention the additional 50% defensive bonus for the Foreign Volunteers. Later on, my Cavs and FVs were promoted to Bliz+March, each one of these units were better than 2 AI units of the same type. And I started getting 2 shot cannons near turn 70. I built plenty of road so that cannons and move 2 tiles and setup and shoot in the same turn. At that point, anything enters my territory get killed on the same turn, even there are a lot of them
As you can see in the turn 79 screen shot, I am maxing out Cavs by available horses, and have plenty of Cannons, the Cavs get to Bliz+March ridiculously fast give all the bonus fighting within my territory. Most cannons got clear terrain bonus, at 45XP when built, it takes 28 turns for them to get to logistics (2 shots) if they get to fire at something every turn, and in this scenario, it is pretty close to that.
In the beginning, the culture I earner from killing invaders far outpaced culture I produced in cities. I dedicated the 2nd city as the GP farm (with NE+Garden) running all 3 types of culture specialists. This city did not produce a single unit yet.
I was able to bribe Portugal to attack Shaka, and it did not take much of my own force to capture Shaka's cities once he were weakened.
I completely forgot about Hermitage until now, so will try to get that in the GP farm. Another GW will be born in 5 turns will burn him on culture.
This is my second attempt as I got back stabbed by Portugal while invading Germany and England in the first try. So in the second try, I just stayed in my land (except quickly killed Shaka) and defended and just reaped cultures from kills.
and +1
