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): airlifting from a city doesn't reduce the airlifted counter. It depends on the ruleset whether this is possible even with zero airlift capacity. - "Unlimited units to destination city" (DEST_UNLIMITED): airlifting to a city doesn't reduce the airlifted counter.

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

mgr_distance - Maximum distance citizens may migrate[]
This setting controls how far citizens may look for a suitable migration destination when deciding which city to migrate to. The value is added to the candidate target city's radius and compared to the distance between the two cities. If the distance is lower or equal, migration is possible.

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.

Any players for which no color is set when the game starts get a random color from the ruleset. - "Per-team, in order" (TEAM_ORDER): colors are assigned to teams from the list in the ruleset. Every player on the same team gets the same color. - "Per-nation, in order" (NATION_ORDER): if the ruleset defines a color for a player's nation, the player takes that color.

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.)
