The cost of my initial research agreement was $300: I entered into a research agreement with an AI in Civ 5, and when it was half finished, it attacked me. Is that money only gone for the two of us, or can we take it back once I`ve taught him a lesson? Civilizations can no longer act with technologies as in previous versions of the game, but civilizations can lead common technological enterprises. Two civilizations at peace can form a research agreement that requires an initial investment of gold and offers both civilizations a certain degree of science as long as they remain at peace.  Prior to the PC version 184.108.40.2062 of the game, civilizations were equipped with unknown technology after a number of uninterrupted rounds of peaceful relations. It is possible that a civilization signs a research agreement for the sole purpose of getting an enemy to spend money that could be used for other purposes; AI civilizations are programmed in such a way that they sometimes use this tactic before declaring war.  British actor W. Morgan Sheppard gives the account of the opening films of the original game and its expansion packs, quotes about discovering new technologies and building tourist sites, as well as introducing the civilization chosen by the player at the beginning of each new game.  World dominance is an option, but the condition of victory has been simplified compared to previous games in the series. Instead of completely destroying other civilizations, the last player who controls his original capital wins by conquering.  Since the Brave New World Expansion Pack, the player must control all the original capitals (including his own) to win by domination. The player can also win by having the highest score in 2050 AD, or all winning conditions can be disabled. These settings, as well as other settings, for example.
B disabling the urban shortcut, can be modified when configuring a game on the “Advanced configuration” screen. The money you put into the agreement is lost. That`s not necessarily a bad thing – if you can put someone in a research agreement before they go to war, they`ll lose the money they could have used to defend themselves. A second expansion pack, Civilization V: Brave New World, was announced on March 15, 2013. It includes features such as international trade routes, a world congress, tourism, great works, as well as nine new civilizations, eight additional wonders and three ideologies. It was released on July 9, 2013 in North America and three days later in the rest of the world. City-states, a new feature in the series, are small civilizations that can interagulate, but are not able to achieve victory. Unlike the great powers, city-states can develop on the territory, but they never create new cities (although they can conquer other cities with military units).
In addition to complete conquest, great civilizations have the opportunity to befriend city-states through bribes or services. City-states offer the player bonuses such as resources and units that increase as players ascend into new eras. In the “Beautiful New World” expansion package, city-states grant allied players additional delegates to the World Congress, which begins in the industrial era. There are three types of city-state in the base game, each with different personalities and bonuses: maritim, cultured, and militarist. Two other city-state types (merkantile and religious) have been added to the Gods & Kings expansion pack to complete new gameplay mechanics. City-states play a key role in diplomacy between great civilizations, make specific demands and give rewards.  In addition to the 18 civilizations available in the standard retail version, other civilizations can be downloaded.   Babylon under Nebuchadnezzar II was announced as a bonus civilization included in the digital editions of Steam and Direct2Drive, and again on October 25, 2010.  Mongolia under Genghis Khan, along with a Mongolian thematic scenario, were added on October 25, 2010 with a free update.  As in previous games, there are several ways to achieve victory….
