I hope that they put different game mechanics for Eastern counties.There are many diffrences between West-East.
Well it depends on what you call east. If you mean the whole east (as in everything east from Europe), i think you cant generalize, as whole east has very few things in common, and remember, in EU3 the Eastern Tech group is Oriental, which is actually mostly Eastern Europe (Russians and Orthodox Christians).
If by east you mean Muslim world, i agree. It doesnt fit very well into western/eastern mechanics, specially when it comes to countries, where in Europe most countries were named after nation or city or something like that, in the Muslim world (and further east) countries were often named by ruling dynasty, and even if that dynasty was deposed the country would just be called after whomever took power. That alone would IMO greatly improve Muslim world, and i would very much like to see this ported to EU3 as its long overdue.
Another thing i can think of right now is the whole heir mechanic thingy. Im not expert on Muslim history, but im under impression that Muslim countries pretty much never got into situation where the ruler didnt have heir, and im not talking just about concept of harem (many wives = many sons = no heirless situation ever) but other traditions as well.
Not to mention that the Ottomans alone deserve to have their own mechanic and stuff.
