Fall from Heaven gets its name from the scenerios that are planned for it. Their are 5 characters in that storyline (the same people that left and right of the title on the main menu) that are planned as civ leaders. I intend to always keep the nomal civ's as well (I couldn't imagine a civ game without my buddy Ghandi). It was pushed to phase 2 because without the scenerios the new civ's are mostly just a cosmetic change. edit (07/20/2008): These plans switched a bit over the development of FfH2. The people on each side of the title (who I believe were Os-Gabella, Capria, Hemah and Valledia) were intended to be major players in a scenario called Tempus Mor. Hemah eventually became a hero, the rest became civ leaders as mentioned orginally. I did think the Civ4 vanilla leaders would stay in the game until FfH2 (what I called phase 2 above), because I didn't see a point in adding new civs and leaders just as cosmetic changes since I couldn't make any of the real changes I wanted. But Haarbal's new leaders and civs were to cool so I added them in.
