I'm curious as to how this affects "split mods." For example, how does this affect the Celtic and Polynesian split? Do they all just get slapped into a Celtic and Polynesian category respectively? Also, how far does this mod go? Are civs like Canada and the Inuits going to stay in their own category/civ? Also, will this change Harun-Al Rashid's "Arabia" into Abbasid if I use mods such as the Umayyads?
