This is vanilla. I have never yet won an emperor game and I may try a replay from a previous save because I'd really like to make it on this one. But I realize in AD 1924 that is not realistic. The scores are pretty close among the 4-5 leaders. Below me are Greece, Japan, England (extinct).
I have fought 3 wars with Mali to my west, the first 2 I started from AD 1100 gaining 4 cities. The last I was defending with no loss/gain. Mali is still a juicy target with lots of wonders and dwindling power. Most dangerous is Arabia, the power leader who now borders me SW after gaining in a recent war with Mali. Other rivals are Rome SE, Spain far S, Greece far SE. In the arctic are colonies of Rome, Spain, America, Arabia that have been subject to a lot of fighting. Sharing another continent with America is Japan.
I just learned about the shrewdness of defensive pacts: Saladin signed with Spain and me, attacked Mali very soon after. If I my cossacks had been around a few turns earlier then I could have picked several Mali cities at fire sales...
