I played a very fun match with Brazil.
Communitas, difficulty 3 (it was a casual game), fast speed, small map and medieval age.
I started in the middle of the continent, with many forests around, two resources of tobaccos and two of tea nearby.
I chose Tradition for obvious reasons, I founded my second city on the east coast, the place had some forest, 3 sheep, 1 fish and 1 horse, was located six tiles away from the capital, shortly after I met the Greeks, which It scared me a bit, so I made a deal quickly.
I founded my third city on the west coast, next to a natural wonder, with two stones, several hills, 1 coral and 1 horse nearby.
Before I founded my fourth city in the jungles, I met the Assyrians. I was friendly with them, made some agreements and soon got a defensive pact.
Fearing Greece, I invested in the Terracotta Army and with that I got enough units to feel safe.
Incredibly Alexander faced difficulty against the barbarians, there were four camps near Athenas, initially thought he was at war, because the city was in the red.
I took advantage of the situation and conquered the Greek capital, which was also a holy city. In the peace agreement he offered me capitulation.
Shortly afterwards I met the Polynesians, who had a very good score, competed with me in culture, technology and had also obtained a vassal.
With the exploration of the bandeirantes I could increase the difference of technologies, and in a short time I met the Celts (Vassalo of Polynesia) and the Danes, the latter was very well militarily.
I spread six embassies, four in my continent and two others around the map. I was able to approve in the world congress measures that increased tourism and generation of great cultural people and besides world religion. But everything was not easy, I lost the Ragusa suzerainty with Open Door, which I could not repel in the later congress, I ended up giving it up.
At one point in the match Denmark accepted to become Vassalo of Polynesia, which I thought was strange since Denmark had the largest army of the game. Soon after this the Celts declared independence.
The game was almost won from there, the only civilization that could challenge me was involved in a war that never ended.
I got the cultural victory before I could use Pracinhas.
And although the sambodromo is a good building, the Great Musicians generated from it were not responsible for my cultural victory I got, the archaeologists were the main reason for winning the match.
edit: I also offered vassalisation to Assyria through a trade agreement.
