Hey, I saw you on Civ 5's Military Occupation Extreme mod. Check this?

"For everyone complaining about this taking everything and want it to be a war-time only effect, I went to the guy who made a mod where I first saw this in action.
On R.E.D. WWII Edition by Gedemon:
I asked 'Is there any way where you can release Frontline as it's own mod?' (Frontline is where, once war is declared, you can walk and claim tiles in any civ that is partied against you).

Gedemon replied:
"1/ simple but maybe outdated is Cultural Diffusion

2/ less outdated (but untested with the last year patch) is this: https://github.com/Gedemon/Civ5-RED-DLL-BNW-Build (this is the project files, you'll need modbuddy to "build" the mod)

in both case use advanced setup screen to set the option as you like.

no support provided, if I had time to provide it, I would already have released the second one... (that should also answer the "can't you just port the WWII code in civ5 ?" question)""

Hey. Yeah, it's actually really simple to alter it so a civ can't train settlers! You do this by modding the civilizations trait (basically it's Unique Ability.) So for a Native American civ like the Iroquois you'd type this into the SDK...

<Trait_NoTrain>
<Row>
<TraitType>TRAIT_IGNORE_TERRAIN_IN_FOREST</TraitType>
<UnitClassType>UNITCLASS_SETTLER</UnitClassType
</Row>
</Trait_NoTrain>

You can find a list of all civs traits in the game files following this path: Assets/Gameplay/XML/Civilizations/CIV5Traits
