So first of all : 

Disclaimer : Any modifications to the game files can produce unwanted effects and throw off the game balance (and can also have some adverse effects the the IA players).

ALWAYS BACKUP ANY FILES BEFORE REPLACING WITH MINES

To find the endless space folder just go to steam library and right click on ES2 --> proprieties --> local files Tab --> browse local files

Although i think i mostly did my job correctly so it shouldn't happen, if you have any problems let me now

So multiple files, i will post more later

Fixed truce behavior :

Truce will now prevent you from hostile action against ships and systems but will keep borders open
DiplomaticRelationStates[Major].xml

Location to drop file :  Endless Space 2\Public\Diplomacy

Fully Colonizable Galaxy 

Removed all tier 4 telluric planets and replaced them by the one 1 level beneath (lava to ash, ice to ocean, baren to artic and desert to arid)

Removed gaz planets from all systems but a few (since there is a minor faction linked to them)

WeightTableDefinitions.xml

Location to drop file : Endless Space 2\Public\GalaxyGenerator

(i will probably post a "magical galaxy" with uber high ressource repartitions and only huge planets in big systems if anyone wants)

Break truce

Will let you declare war again after truce has been forced on you

ForeignAffairsConstructibles[Terms].xml

Location to drop file :  Endless Space 2\Public\Diplomacy

Oddly enough the IA players will respond correctly knowing you broke a truce, i think a higher tier diplomacy tech (unavailable yet) may provide the ability to break truce since these dialogues were already implemented




More to come



Enjoy your game ;)
