Increased tech cost to have (much) longer games, late game techs take 1 turn to research

[BornDownUnder]

In DefineChanges.sql there are the below lines relating to policy costs if you feel concern regarding policy pacing:

UPDATE Defines SET Value = 50 WHERE Name = 'BASE_POLICY_COST';
UPDATE Defines SET Value = 2.22 WHERE Name = 'POLICY_COST_EXPONENT';
UPDATE Defines SET Value = 4 WHERE Name = 'POLICY_COST_INCREASE_TO_BE_EXPONENTED';
UPDATE Defines SET Value = .20 WHERE Name = 'POLICY_COST_EXTRA_VALUE';

Have the old more direct tech cost per era variables been removed? I can't locate them, eg:

Ancient Era: 75
Bronze Era: 125
Iron Era: 150
...

They were quite fine-tunable and would likely solve OP's issue.

I just pretend that the population of the world are dimwitted culture vultures. Rich in tradition, song, dance, and creative expressionism. It just takes them along time to figure out how to add, subtract, and blow things up.
