To expand a little......
I took out the Americans first, then Pesia. I started cramming as many towns as possible all outside my core, building temples, libs, and later universities and colosseum with disbanded Cavs as th shield source. After the southern half of my continent was secure I started warring up top, swinging from west to east. I had a checkpoint set up on the eastern land bridge so I felt that was the best way to keep Iroquois out of my core.
From that point on it was rush all the culture buildings I could. The other content sent a few troops now and then but it was over.
Thanks for the game.
