it's extra religion groups you cannot add, and I said I wasn't sure that was intended. Now I could be wrong, and at the end of the day we have never promised every possible aspect of our games would be moddable, but that wasn't the impression I got the last time I spoke to Doomdark about modding CK.
If it is the case that you guys locked out the creation and playability of new religion groups, well... maybe you guys should considering changing this in a patch. I agree with you guys on Muslims and Pagans. We'll get access eventually, we just have to be patient while the DLC for it is in the oven. But there are other users here who really wanted to do things like add in the Jewish Khazars and other groups, and they shouldn't be prevented from doing that with modding, IMO. I'm not one of those users who pretends to be an expert on programming PI games so I'm not going to tell you what is and isn't easy to change. But if it is a case of changing a no to a yes or a 0 to a 1 in the hardcoding, please consider opening religions to modding if they really are locked as you said may be the case. Thanks.
