Principia Moderni (Map Game)

Principia Moderni, or "The Beginning of the Modern" in Late Latin, is a map game beginning in the final days of the Middle Ages in Europe, and the early days of the Ming dynasty in China--1420 C. E...The House of Hohenzollern are the Electorates of Brandenburg--though most of the power in the Holy Roman Empire still lies with the Habsburgs, Joan of Arc has defeated the English at Orleans, the city of Mexico is founded by the Aztecs, the Timurid Empire has united Central and West Asia, and the Yongle Emperor sends out Zheng He to voyage westwards. It is a turbulent era, in other words.

Rules
You can hire raiders/pirates and make them raid any nation's ship, but this greatly reduces that country's relationship with your nation.*
 * The main goal of these rules is to keep it realistic, therefore every turn must be plausible--one cannot take over the world in 10 turns
 * Exploration takes one turn.
 * Any land which one wants to invade still has inhabitants--one must detail how they are dealt with
 * Pro Tip: Incorporating linguistic dominance is useful
 * A turn is taken by doing an action in that given year, an action can be diplomatic, militaristic, etc.
 * Every person must do an action every year, but only one action.
 * At the end of each 20 years, a map is to be made. Every person must edit the map according their nation's actions. If you have not made an action that requires the map to be changed, do not change the map.
 * Every map must be saved as a .png.
 * Every person will 'call' a nation before the map starts--ONLY ONE NATION per PLAYER. If there are leftover nations we will decide if people get a second nation.
 * The creator of this game, Cosman246, has the power to grant and regulate technology for every nation, as well as regulate plausibility. They also have the right to create random events in any and every nation throughout the course of the game.
 * Actions like espionage are allowed and will be detailed later.
 * If a nation wants an alliance with you, your nation can bargain (example-Portugal wants an alliance with Spain, but Spain will only join if Portugal gives its land claims in South America.)
 * There are supernational confederations (e.g. the HRE, the Kalmar Union), and they function like alliances
 * The game ends in 2010
