Greetings!
Firstly, I agree that Turkish and Iran-based nations should be kept separate. As well as Arabic as such. There are simply too much material to squeeze into 1 nation per era.
This is also a thread which we started some time ago considering Arabian-based nations:

Please say what do you think about it, especially as LA was planned to be Ottoman Empire-based. I do not know how much Aezeal progressed in his work on EA since, but MA is almost finished. It's based on 10th-century Arabic states of Middle East, which used many Turkish mercenaries and had some Persian influence. I also have some problems with making art
, but I think they will be overcome soon...
NTJedi also plans something, but refuses to disclose it for now.
As for Tamerlan empire it used mostly Mongol-style military and I'm not sure that we have possibility to model it adequately under current engine. Furthermore, LA Tien Chi is already based partly on Mongolian Yuan dynasty in China...
And considering Russia I heard that MA nation called Vanarus is planned, with human and Van troops (Van sacred) and using magic including Nature. As current Bogarus doesn't strike me as logical (heretics and orthodox church together, for example), I'm also working on a mod which splits this nation in 2. It's thread is here:

It's also lacks graphics for now, but they are underwork currently. The version uploaded there is for Dom 3.15. I'm currently trying to kill bugs appearing in it under 3.20 and will update soon. Any comments are welcome.
