In the file:
(1) Community Patch (v 88)\Core Files\Core Values\CoreDefine.sql
Change those values:
'BALANCE_CORE_WORLD_WONDER_SAME_ERA_COST_MODIFIER'
'BALANCE_CORE_WORLD_WONDER_PREVIOUS_ERA_COST_MODIFIER'
'BALANCE_CORE_WORLD_WONDER_EARLIER_ERA_COST_MODIFIER'
The aforementioned code doesn't seem to work? I reduced the numbers on these lines, but the in-game tooltip still says the higher numbers...? Somebody help?
