Everything rules sensitive was translated by hand (units, technologies etc.) or it is using the default German translation that came with the game.
Due to the amount of work, all events and decisions were translated using https://www.deepl.com/ which is an AI translator that returns pretty good results.
The AI translations were afterwards proofread by Sloane and by myself and tested ingame.
As it is currently not possible to add new languages via a mod, the Spanish version of the game is overwritten (!).

Installation:
Copy the complete content of 'SC-ACW - Deutsch' into the Strategic Command installation folder (where the SC3-Civil War.exe is located).
This will overwrite the Spanish version of the game (!).
Then click on the German flag in the bottom right corner of the game's main menu.
If in future game version new events are added this mod needs to be updated accordingly and might not be compatible. You'll most likely get an empty text box if the event hasn't been translated.
