"PETRÓLEO S.A." is about companies that produce and sell oil in the international markets. Every company will first have to prospect and find oil. They also will have to build prospection towers, pipelines and deposits to store it. Only then are they prepared to produce oil. But all this only matters if you're able to rent an oil tanker to transport your oil to the international markets, where you can sell it. And when you do, do not forget to check the oil price in the market. Maybe it's not the best timing for you. Game ends as soon as any player reaches 2.000 zilions.
