Pooh. Here's how it should be:
Tribes at the start of the game:
Hittites
Indoranians
Greek
Italians
Armenians
Germans
Albans
Slavons
Tocharians
Celts
Balts
In this particular game the Hittites and the Tocharians get eliminated early. The Indoranians fight a civil war splitting into two: Indians and Iranians. Same with the Italians who split into the Oscans, the Umbrians and the Latins. The Latins eliminate the Oscans and the Umbrians. Elsewhere the Celts get unhappy and start fighting among each other splitting into the Gauls, the Irish and the Brythons. The Gauls get wiped out.
Iranians lose their capital and the civ breaks into the Avestans, the Persians and the Scyths. The Scyths get conquered and are out of the play. Everybody ignores the Avestans 'cause nobody wants their tiny and poor plot.
The Latin empire starts a war with the Germans. The German government collapses and two distant colonies, the Goths and the Scandinavians declare independency. The war continues and the Anglofrisians split from the Germans. Finally the Germans manage to take revenge and with the fortunes of war changing now two Latin colonies, the French and the Spanish show the boot to the Latin emperor and form their own civs. Later the Germans lose the colonies of the Saxons and the Flemish who go their own way.
The Scandinavians have no-one to fight with so they start squabbling among themselves splitting into the Icelandians, the Norse and the Danes. The Goths get eliminated. The Balts are too close and get drawn into the mess splitting into the Lithuanians and the Lettish. The Lettish get wiped out.
As if their isles aren't small enough the Scots declare independency from the Irish and the Brythons split into the Welsh and the Bretons. The Saxons conquer the Bretons. The Anglofrisians split into the English and the Frisians. The English conquer the Saxons and later the Welsh and the Scots.
A distant English colony descends into civil disorder because of too much corruption. They declare their independency and form the American tribe...
