Philosophy – Neosophism
This mod aims to give the player a more mystery cult oriented flavour of late Hellenic paganism. One religion is preached to the masses while the educated elite are free to make up their own philosophies and ideas about the divine.
This mod also allows you to rebuild the Colloseum, Parthenon and Library of Alexandria among many other things.
If you’re having problems with conversions there are certain buildings that you can build to reduce the conversion penalty.
Unfortunately this mod is probably not compatible with any other mod that adds new religious doctrines (at least core tenets) as it seems it’s impossible to mod compatability for that. (If you have any information about how this can be done please contact me)
