Europa Universalis III
Europa Universalis III is a grand strategy video game developed by Paradox Development Studio and published by Paradox Interactive. The game was released for Microsoft Windows in January 2007, and was later ported to OS X by Virtual Programming in November 2007. The player controls a nation and handles matters concerning war, diplomacy, trade, and economy. The original game without expansions starts in 1453, right after the Fall of Constantinople, and continues to 1789, just past the beginning of the French Revolution. The expansion Napoleon's Ambition extends the end game year forward to 1821, whereas the expansion In Nomine moves the starting year back to 1399, making it the longest as far as gameplay time in the series thus far. Europa Universalis III was the first to use Paradox's new 3D engine, Clausewitz Engine, that required user systems to meet the Pixel Shader 2.0 specification. The map has 1,700 land and sea provinces encompassing most of the world, with 250 playable historical nations. The game also uses elements of other Paradox games such as Crusader Kings, Victoria, and Hearts of Iron II. Gameplay Players begin the game by choosing what date they would like to start their campaign and which country they would like to play as. Once in game, players can shape their countries in many different ways. Forms of government include various kingdoms, republics, theocracies, and tribal governments. Players can influence a nation's society and values by adjusting "sliders" such as free trade/mercantilism, and may hire court advisors such as Wolfgang Amadeus Mozart. As the game advances, players can pick "national ideas" such as Liberté, Égalité, Fraternité, which give specialized bonuses. The game has over 300 playable countries, including giants like Ming China, regional powers like Bohemia and Kazan, and tiny nations like the Maldives. Without formal victory conditions, players sometimes set goals for themselves like raising a minor city-state to world prominence. The world map includes some 1,700 provinces and sea zones. Many provinces in the Americas, Africa, and Oceania are not owned by any country, allowing for colonization. Economics in the early modern era is simulated by taxes and production income from provinces, as well as trade. National merchants compete in "centers of trade" such as Venice and Lübeck, and nations focused on trading income (e.g., Holland) enjoy significant advantages. Nations which mint too much currency, or are over-reliant on gold mining, are penalized by inflation. Technology investment is important in the long run; the game does not use a Civ-style tech tree, but instead has several different technology categories, which unlock new military units and buildings. Diplomacy is rather detailed: royal marriages, insults, alliances, trade embargoes, and so on all affect relations between countries. Players are able to gain control over other countries peacefully through personal unions and vassalage. Early international institutions such as the Holy Roman Empire, the Papal Curia and with the Divine Wind expansion the Shogunate are simulated in some depth. Every country has its own culture and religion, a frequent source
