airliftingstyle - Airlifting style
This setting affects airlifting units between cities. It can be a set of the following values: - "Allows units to be airlifted from allied cities" (FROM_ALLIES). - "Allows units to be airlifted to allied cities" (TO_ALLIES). - "Unlimited units from source city" (SRC_UNLIMITED): note that airlifting from a city doesn't reduce the airlifted counter, but still needs at least 1. - "Unlimited units to destination city" (DEST_UNLIMITED): note that airlifting to a city doesn't reduce the airlifted counter, and doesn't need any.

DEST_UNLIMITED: "Unlimited units to destination city"
Default: empty value
allowtake - Players that users are allowed to take
This should be a string of characters, each of which specifies a type or status of a civilization (player). Clients will only be permitted to take or observe those players which match one of the specified letters. This only affects future uses of the "take" or "observe" commands; it is not retroactive. The characters and their meanings are: o,O = Global observer b = Barbarian players d = Dead players a,A = AI players h,H = Human players The first description on this list which matches a player is the one which applies. Thus 'd' does not include dead barbarians, 'a' does not include dead AI players, and so on. Upper case letters apply before the game has started, lower case letters afterwards. Each character above may be followed by one of the following numbers to allow or restrict the manner of connection: (none) = Controller allowed, observers allowed, can displace connections. (Displacing a connection means that you may take over a player, even when another user already controls that player.) 1 = Controller allowed, observers allowed, can't displace connections; 2 = Controller allowed, no observers allowed, can displace connections; 3 = Controller allowed, no observers allowed, can't displace connections; 4 = No controller allowed, observers allowed

Minimum: 0, Default: 20, Maximum: 500
aqueductloss - Percentage food lost when city can't grow
If a city would expand, but it can't because it lacks some prerequisite (traditionally an Aqueduct or Sewer System), this is the base percentage of its foodbox that is lost each turn; the penalty may be reduced by buildings or other circumstances, depending on the ruleset.
Level: Rare.
Category: Economic.
Minimum: 0, Default: 0, Maximum: 100
armisticelength - Length of Armistice before Peace
This setting sets the turn length of the Armistice that occurs when two nations agree to a Peace treaty.

autoattackstyle - Style for server side autoattack.

Level: Situational.
Category: Military.
0: ➤ DEFAULT: Units on adjacent tiles generally attack enemy units if they have better odds attacking than defending OR if the enemy has the flag "Provoking". Exception: a single unit in a city not wanting to leave the city undefended if it loses. 1: ➤ PROVOKED_ONLY: "Provoking" units ONLY will be autoattacked. Rulesets use "will_never" and "Provoking'" flags to make reqs for which units proactively attack specific types. Only units with the Vigil order will autoattack, giving players tactical control. This is used to minimize 'baiting' and other unnatural dynamics: e.g., a ruleset can be coded so that only Fighters auto-attack other Air units,
Default: 0
autosaves - Which savegames are generated automatically

citymindist - Minimum distance between cities
When a player attempts to found a new city, it is prevented if the distance from any existing city is less than this setting.

A value of 1 removes any such restriction on city placement.
Level: Situational.
Category: Sociological.
Minimum: 1, Default: 2, Maximum: 11

city_output_style - Whether to replace city output behavior with WYSIWYG
With the default setting of 0 (disabled), classic behavior decides city output when a city grows or shrinks: citizens are re-arranged to new tiles and specialists AFTER food, shields, and luxury are calculated, but BEFORE science and gold are calculated. This gives a small bonus to growing cities, but has a side- effect of overriding the science and gold outputs for the tile and specialist choices the player selected in the city. If this value is set to 1 (enabled), then city output is WYSIWYG ("what you see is what you get"); that is, it is calculated exactly according to the tiles and specialists the city selected prior to growing or shrinking, unless: 1) a newly produced improvement would alter those with a bonus. 2) a newly produced settler decreases food surplus from its upkeep.

Category: Sociological.
Default: enabled
mgr_nationchance - Percent probability for migration within the same nation
This setting controls how likely it is for citizens to migrate between cities owned by the same player.

migration - Whether to enable citizen migration
This is the master setting that controls whether citizen migration is active in the game. If enabled, citizens may automatically move from less desirable cities to more desirable ones. The "desirability" of a given city is calculated from a number of factors. In general larger cities with more income and improvements will be preferred. Citizens will never migrate out of the capital, or cause a wonder to be lost by disbanding a city. A number of other settings control how migration behaves: 'mgr_turninterval' - How often citizens try to migrate. 'mgr_foodneeded' - Whether destination food is checked. 'mgr_distance' - How far citizens will migrate. 'mgr_worldchance' - Chance for inter-nation migration. 'mgr_nationchance' - Chance for intra-nation migration.

This setting does not affect likelihood of nuclear fallout from detonation.
Level: Vital.
Category: Geological.
Default: enabled

nukes_major - Allow nuclear detonations
Allow players to create major thermonuclear weapons. If turned off, this will have no effect on standard fission nuclear weapons; but in rulesets which require this setting to be on for thermonuclear fusion weapons, they will be disallowed for the current game.

Default: 13
pax_dei_set- Whether the game considers Pax Dei in effect at game start.
Usually, this gets set in a game when the Pax Dei wonder is built. " However, it is possible to enable 'pax_dei_set' at game start. This activates the ruleset effects for the Pax Dei wonder at game start, for exactly 'pax_dei_counter' # of turns. Note: this intentionally disallows Pax Dei from being made by any player. Thus, this setting can be used to enable Pax Dei wonder effects at game start and/or completely disable the Pax Dei wonder in the current game (if 'pax_dei_counter' is set to 0.) Also see: 'pax_dei_counter'.

startpos - Method used to choose start positions
The method used to choose where each player's initial units start on the map. (For scenarios which include pre-set start positions, this setting is ignored.) - "Generator's choice" (DEFAULT): the start position placement will depend on the map generator chosen. See the 'generator' setting. - "One player per continent" (SINGLE): one player is placed on each of a set of continents of approximately equivalent value (if possible). - "Two or three players per continent" (2or3): similar to SINGLE except that two players will be placed on each continent, with three on the 'best' continent if there is an odd number of players. - "All players on a single continent" (ALL): all players will start on the 'best' available continent. - "Depending on size of continents" (VARIABLE): players will be placed on the 'best' available continents such that, as far as possible, the number of players on each continent is proportional to its value. If the server cannot satisfy the requested setting due to there being too many players for continents, it may fall back to one of the others. (However, map generators try to create the right number of continents for the choice of this 'startpos' setting and the number of players, so this is unlikely to occur.)
