And I am taking my time to release all the planned features. Shamanism and Neandertals, as I envision these features, are a quite deep and complicated matter to script, even on a basic level. There are many spirits, many ways to deal with them, and many recompenses to chose from (you know, Rigale is a lot about adding variety to Warband...). The Epidemics features should be somewhat easier to implement, complete with effects on villages towns castles and prosperity, and the medical quests.
