It is the late Republican period of Rome, and you are the leader of one of the factions in the city, competing for power in the Senate. You are increasing your wealth by buying up resources, then using your position to sell them to the state for fat profits. With the resulting cash, you then "buy" more Senators, controlling yet more votes in the Senate. Rome is constantly in conflict, and you know that at some point wars will increase to the point that the Senate will choose to centralize power and appoint a single leader. At that moment, the leader of the faction with the most Senators will be made Caesar.
