the 1 i read said it was for both
Uhhh, what? That's not true. Lying will only make you look bad. The first line of 2.0E's readme says the following:
Sins of a Galactic Empire (SOGE) 2.0E release for Sins of a Solar Empire Entrenchment v1.053 and v1.051
There were versions for original Sins, but those versions have long since disappeared and their download links dead. Further, there's this nice little section later on:
Entrenchment 1.051+ (until Ironclad breaks it again)
Odds are this will work with Entrenchment 1.041, but this has not been tested. If you want to backport the mod to a previous
version feel free, but it is a tremendous amount of work.
Please go get Entrenchment or Trinity; SoGE will not work with base Sins.
