Hey, I'm new to modding so I'd love all the help I can get.

I would like to create a Phoenician faction, similar to how the Judean and Palmyran rebels appear around Aelia Capitolina (Jerusalem) and Palmyra but around Tyre with a roman style or maybe a carthage rebel faction around Carthago in Africa. I'd also like to edit Semitic paganism to reflect the punic religion and have it as their starting religion, (baal, tanit, melqat, astarte) since the ai almost never lasts as semitic pagans and I know you can't add a new religion outright.

I've never really modded before and I know this is probably going to be a lot harder than I'm thinking but any tips on how to start and go about it would be much appreciated. If this is meant to be in another thread or anything like that let me know and I'll change it lol, I usually just play games not edit them.
