In Vanilla Civ VI, every one achieves future era when year is 1600 so its kinda dumb.
This mod seems to fix that issue, hovewer it is difficult to find that balance.

These settings seems to OK. What do you guys think?

Science Cost: 1,5x -- Culture Cost: 2x
Tech/Civic Cost Scaling: High
Eureka/Inspiration: %33
GP Scale: 1,2
World Era Scale: 1,1

Do you think these are good?

Other 2: (Haven't tried yet)
