'Game Math' Questions

[starrywisdom]

I'm not sure if these are hidden somewhere(I kinda thought there would be a thread for 'unannounced math' somewhere) but I'm looking for some information on the 'math' for the game that isn't produced in game. Some that come to mind are below; any links or answers would be greatly appreciated.

[Note: I know base numbers will differ depending on length and possibly other factors, so if we know %'s that's fine ]

• Policies: What are the math formulations that dictate the cost of policies? How much does adding another city increase it by? How much does each policy increase by when completing a policy.
• General: When playing on non-standard is there a % reduction/increase globally to how long everything takes, or does it vary?
• Playing with teams: When you add someone to your team, research costs go up it appears? If so how much does it increase by per person on the team?

most of this isn't really hidden, it's just in various places in the xml, like the defines and handicapinfos table

the policy cost formula has changed to have a multiplier of 3 and exponent of 2.
the cost of a single policy is

floor( 25 + ( 3 * ( policy number - 1 ) ) ^ 2.01 * (1 + number of cities policy cost mod * ( number of cities - 1 ) / 100 ) * policy percent handicap modifier * game speed culture percent * (100 - cristo redentor + piety finisher reductions) / 100 / 5 ) * 5

number of cities policy cost mod is 15 base, 10 with representation, lower with larger than standard map sizes
policy percent handicap modifier is .5 on settler, .67 on chieftain, .85 on warlord
game speed is .67 on quick, 2 on epic, 3 on marathon
cristo + piety finisher are 10 each if you have them

the floor( x / 5) * 5 is just to round down to the nearest 5

Thanks, I browsed through it yesterday I believe and don't remember seeing it.

That being said, I don't consider having to go into the games 'files' as visible. I was refering to information that's not provided on hovering over items in game / civlopedia
