It does feel like we're heading for including the Israelites as a civilization.
It would be hard to implement them, I think. They would get tossed around between the Egyptians, Babylonians (Sumerian?), Carthaginians and later on Rome West and East - Just as history told us. The only thing I could see happening is to let the British Mandate of Palestine and later on Israel emerge in the area, but that would be very late-game, no?
beating Arabia to Divine Right takes a concentrated effort that the AI will virtually never accomplish
I've seen China doing this countless times, when playing on Emperor.
One time even Rome. Rome was on steroids in that game, tho... They would stop for nothing.
All that aside, I have something to say, too:
I would be very fond of including Shinto as a local religion. It would go perfectly with Buddhism (see Zen-Buddhism etc.) and could even serve as an extended gameplay mechanic.
Here's what I'm thinking: If a potential aggressor comes by and annexes the Japanese islands and does not take immediate action to purge Shinto from the captures cities they're gonna have a bad time. Massive loss of stability, unhappiness, revolts something along those lines is what I'm thinking.
It would make sense, too, no? Due to their extremely strong culture, the Japanese spirit must be broken first, to come even close to ruling them.
