Rise of Empires is a mod for Crusader Kings II. The mod starts at 1500 BC at the start of the Empires era and ends at 769 AD the earliest bookmark in CKII. For the earliest bookmark I used the holocene calendar year of 8500 (1500 BC) in game since the game engine can't go backwards and the AUC or the Gregorian calendars don't cover this time frame. The mod is currently WIP but I will try to post updates of progress, any suggestions or ideas are GREATLY appreciated.
This is still a work in progress, I'm thinking of adding south and east arabian cultures to create some diversity and conflicts in the region in the long turn, before they unite under the bedouin arabic culture later on.
