Recently, I had an idea to make the middle east spicier: tribal mechanics. Countries could choose specific tribes to dominate their government, and fulfill missions based on the tribes geopolitical history. For example, the Kurds could form the Ayyubids in a mission. Iraq could have the Assyrians take power and form the Assyrian Empire that way. I know there are A LOT of tribes, so lets only add the ones that had significant empires post-Hellenic age and have 5% or more of the population included. Turkomans could also be represented.
A civil war mechanic could also be highly useful for this
Thoughts? (please don't argue about middle east geopolitics in the comment and focus on the actual idea)
