Well I'm going to buy it when it's a daily deal on steam. And I would like to see Jews/Judaism there. So I do can participate in this discussion to some extent.You basically shouldn't even be talking about this because the only point of the discussion is Judaism in relation to the game, particularly in the 867 period. Besides the Khazar Jews, the kingdom of Semien ( http://en.wikipedia.org/wiki/Kingdom_of_Semien ) in east Africa peaked around this time.
Further, even if you don't think the Khazars are "Jewish" because of your racist "not true Jewish ethnicity" nonsense, the fact is that the Khazars WERE NOT TENGRI. So we have a problem where we have a large Khazar state that called itself Jewish, that you say is not "real Jews" but that the developers then call Tengri.
So even if you were right that Khazars aren't "Jewish" it certainly doesn't make them Tengri.
I never said they were not Jewish. In fact I explicitly stated that Jews are a non-exclusive ethnic group and that according to Jewish tradition converts to Judaism doesn't just convert to the religion but becomes part of the people as well. Kinda like an adoption on grander scale. I also said that while there is such a thing as a Jewish ethnicity (again a non-exclusive one) I wouldn't know for sure that it is a prerequisite for being an adherent of Judaism.
