does it work with et?

if you also give Kamchatkan a colonist they might actually be playable, though it's not exactly historical.

Neat. There was a mod a loooong time ago that had this premise, but it got abandoned. Nice to see a new one.

• Western Aryan = Caravan Power: +10.0% -> +10% nobility/rajputs/maratha loyalty equilibrium
• Burman = Diplomatic Reputation: +1.00 -> Vassal Force Limit Contribution: +10.0%
• Evenki = Land Force Limit Modifier: +10.0% -> Regiment Costs -10%
• Japanese = Aggressive Expansion Impact: -10.0% -> Army Tradition From Battles +50%
• Kamchatkan = Colonial Range: +25.0% -> Light Ship Cost -10%
• Tai = Tolerance of Heathens: +2.00 -> Cavalry Cost -10%
• Kongo = Chance to Capture Enemy Ships: +10.0% -> Missionary Strength +1.0%
• Sahelian = Movement Speed: +10.0% -> Caravan Power +10.0%
• Aridoamerican = Vassal Force Limit Contribution: +10.0% -> Looting Speed +20%

You can DM me on Steam or Discord for more info, but in general i feel like much of asia got unfitting ones

What I would have done:

• Celtic = Land Fire Damage: +10.0% -> Shock Damage +10.0%
• Nordic = Land Attrition: -10.0% -> Naval Attrition: -10.0%
• Baltic = Trade Steering: +10.0% -> Diplomatic Relations +1
• Byzantine = Warscore from Battles Modifier: +10.0% -> Prestige From Battles +50%
• Levantine = Core-Creation Cost: -5.0% -> Trade Steering +10.0
• Ugric = Idea Cost: -10.0% -> Land Attrition: -10.0%
• Central Indian = Placed Merchant Power Modifier: +10.0% -> Infantry Cost: -10.0%
• Hindustani = Infantry Cost: -10.0% -> Land Fire Damage +10.0%

Diplo for Byz is actually not bad.

or an admin buff.

I think Byzantine might be better set to Diplomatic Reputation +1, tbfh. After all, they were THE Roman Empire.

@Elements08 theres not much I can do about that, sorry. I had noticed the previous version wasn't working with my usual playset of mods (and presumably other people's), so I guess that's the tradeoff.

the latest update made the mod incompatible with other mods that add cultures.

it's pretty obscure and not really mentioned anywhere on the wiki, i only ever noticed because when modifiying that file i always saw comented out lines for scandinavian (ofc, pdx) group cultures that had modifiers and i decided i wanted to see what they did if i uncomented them back in.
btw, the ones pdx has for scandinavian are something like this:

#country = { land_forcelimit_modifier = 0.25}
#province = { local_build_cost = -0.10 }

@ɌƗȻꝀŦɆɌ I wasn't actually aware of that, thanks, I'll try and update the mod to work that way instead when I get the time (as well as do more rebalancing that people have pointed out)

Just so you know, you can actually put this modifs directly into the common/cultures/00_cultures file, no need to make events and add event modifiers
it works the same way as enabling banners, caroleans and some other special units/ships, those are technically country/province modifs added directly thru the culture file
you can add:
modifs for countries of both the whole culture group and individual cultures (they overlap)
and you can also add valid province modifs that will individual affect every province, also for both culture group and individual cultures (they also overlap)

These modifiers are great but some are really OP like:
• Cushitic = Religious Unity: +25.0%
• East Slavic = Attrition for Enemies: +3.00
• Carpathian = All Estates' Loyalty Equilibrium: +10.0%
• Iberian = Colony Cost Modifier: -20.0%
• Malay = Combat Penalty when landing: -2.00

West slavic bonus is absolutely ♥♥♥♥♥♥♥

Very cool.

5% morale of navies is very low. Maybe replace it with ship trade power since that's more useful.

@krummavisur thanks for the ideas, have now updated the mod :)

Change proposal
-Strong bonus-
• French = Yearly Army Tradition Decay: -5.0%
this is most powerful.[army trd decay]
This has a big effect even with a small value.
Therefore, I suggest changing the value as follows.
Army Tradition Decay:-5.0%->-1.0% OR -2.0%.

• East Slavic = Attrition for Enemies: +10.00
The bonus type itself looks good, but the value are excessive.
How about +2 or +3 instead of +10?

-weak bonus-
• Iberian = Colonial Range: +10.0%
I think this bonus is too small for them.
You'll have to change the bonus type, or raise the figure quite a bit.
Here's my suggestion.
Colonial Range:+10%->50%
OR
colony_cost_modifier:-0.2 *this mean colonial maintain cost -20%.

• West Slavic = Yearly Prestige: +0.50
vaule is so weak. i think change to +0.5->+1.0

• Central Indian = National Supply Limit Modifier: +10.0%
I think this is a useless value and useless type.
How about tax rises instead? global_tax_modifier = 0.10 ?

West Slavic bonus completely sucks comparing to other groups.
