Doesn't appear to be working. Is there some specific load order?

...So yeah, sorry i'm using your mod as a basis for my tweaks XD
It's just this mod is so simple to understand, it's helping me to learn how to mod some stuff.

Also... in case anyone wants to have units to be 6 times faster, so you could walks as much in one Online Speed turn as in six Marathon Speed turns (Because Marathon is 6 times slower than Online)

UPDATE Units
SET BaseMoves = ROUND(BaseMoves *6)
WHERE BaseMoves > 1;

You can also modify /2 into /6 if you want to have Online Speed build costs on Marathon Speed ^^
Tho, it could break the era flow, as you could spam lots of cities and get way ahead in tech and civics...

So you can also add:

-- Era Gates -- default 20/-20
UPDATE GlobalParameters SET Value = 900 WHERE Name = 'TECH_COST_PERCENT_CHANGE_AFTER_GAME_ERA';
UPDATE GlobalParameters SET Value = -90 WHERE Name = 'TECH_COST_PERCENT_CHANGE_BEFORE_GAME_ERA';
UPDATE GlobalParameters SET Value = 900 WHERE Name = 'CIVIC_COST_PERCENT_CHANGE_AFTER_GAME_ERA';
UPDATE GlobalParameters SET Value = -90 WHERE Name = 'CIVIC_COST_PERCENT_CHANGE_BEFORE_GAME_ERA';

This would make every era be it's own era ^^

So in your workshop\content\289070\3199933813 find HalfCost file, and add there at the end:

-- More Mods
UPDATE Districts
SET Cost = ROUND(Cost /2)
WHERE Cost > 1;

UPDATE Districts
SET CostProgressionParam1 = ROUND(CostProgressionParam1 /2)
WHERE CostProgressionParam1 > 1;

UPDATE Units
SET CostProgressionParam1 = ROUND(CostProgressionParam1 /2)
WHERE CostProgressionParam1 > 1;

Districts still build slowly, which is very noticeable in Marathon, as Wonders take less turns to build than districts

Districts and some Units have higher cost the more you build of them...

So i've decided to update this mod:

Its possible only for units, not buildings?
