Culture

Culture is a game concept new in Freeciv 2.6. Cities and nations in the game may now generate points of their cultural level that may influence the game and final scores.
Culture is divided by range and duration:
 Culture-generating effects
Type 	Range 	Range
Type 	City 	National
Type 	Belongs to a specific city	Belongs to a whole nation
PerformanceMomentary value, does not accumulate 	Performance 	National_Performance
HistoryAccumulated each turn, since v.3.1 may grow by itself at an interest rate	History 	National_History
Sum of history and performance is spoken as "culure" in general. It may be tested in the ruleset by a "MinCulture" requirement of the corresponding range. History of a nation or a city may decrease if the effect is negative but not below 0.
The effects, enabled in a ruleset, may generate certain amounts of culture. This is the table for standard rulesets that enable it:
Building 	City history per turn	City history per turn
Building 	Experimental 	Civ2civ3
Cathedral 	- 	+3
Colosseum 	+1 	+2
Library 	+1 	+1
Palace 	+2 	+1
Temple 	- 	+1
University 	+1 	+2
Ecclesiastical palace(without Palace) 	- 	+1
Research Lab 	- 	+3
Different wonders 	- 	From +2 to +6
Points for cultural victory(if enabled)	15000 	18000
Different wonders in Civ2civ3 generate from 2 to 6 history per turn.
Cultural victory may be enabled by game settings. The minimal amount of culture necessary for it is defined in game.ruleset as victory_min_points but to obtain the victory the leading player must also overdo the second culture scorer for at least a given percentage victory_lead_pct (usually 200%, i.e. one must have three times more than the another).
Another gains from culture may be achievments of types "Cultured_City" and "Cultured_Nation" (Civ2civ3: gained for 1000 points in a city and 10000 for a nation); achievments of these and any other types may bring additional one-time culture bonuses to the player's history (Civ2Civ3 Cultured_City gives +100).
Yet another city culture effect is better migration score of the city (defined by migration_pml, amount/1000 equivalents this portion of a happy citizen in a city with no buildings or trade/lux/science surplus or about a half of it in a very abundant city).
National culture of both types is a sum of city cultures of all the cities of the nation and the player-ranged national culture effect. If one cvilization captures a city of another, they get all the city's history to their value. Other ways to obtain some culture:
* By Lua methods (Player|City):add_history(); the checking method is (Player|City):culture().
* Since v.3.1, history may grow by itself on certain points per mil each turn (history_interest_pml).
