I've had to forcefully stay away from the game for the past week and half and took the chance to translate -whenever possible- all the faction names into English. Some literary license was taken here and there because google translate didn't have translations for some (most?) of the names and I didn't have access to the original names used in Stainless Steel. Still, I think the result is OK, definitely an improvement over vanilla SSHIP where most of the time I don't know who's who or what's what when it comes to factions/diplomacy.
The file must be placed into the SSHIP's data/text/ folder, overwriting the file there. Enjoy!expanded.txt
