Really interested in this. I just merged it with Ancient Religions Reborn for my own game--here are the conflicting files (+ the paganify event) which I tweaked in github. Haven't tested much except to see that it boots up. There are probably a lot of things in ARR that limit scopes to pagan_group that I need to make say that or african_group, but for now this suits me.
I just throw one file on top of another and overwrite, then throw the attached files on and overwrite again. It's better practice to something to make it dependent on both though.
After ARR's Paganify decision.
Thinking about including 633's Cushitic/Waaq religion (and still am for my home game), but it wouldn't work as a patch because I'm only interested in the religion and some other features and not the whole bookmark at 633 with no de jure kingdoms in Eastern Europe thing.
