Civilization V: The Swedish Saga, part 1 (4000 B.C. to 430 A.D.)
The League grows stronger
50 B.C.: Austria joins the Continental League, leaving only the weakened, warmongering Germans and the aloof, enigmatic Celts outside the circle.
55 A.D.: Buddhism is founded somewhere across the sea.
70 A.D.: The Danes declare war on the Germans, reduced through centuries of conflict to only the city-state of Hamburg. The Danish general proclaims that he will wipe what remains of their bloodthirsty empire from the face of the earth once and for all.
100 A.D.: A formal Swedish currency is adopted.
The same year, Swedish sailors encounter the Greek-allied City-State of Vatican City.
Greece is pretty boss when it comes to gathering allied city-states, which is almost certain to put us at odds if I'm going for a diplomatic victory. The Vatican is (as you might expect) a Religious city-state, so they'll respect me more if I can found and spread my own religion.
